I'm so happy my story has inspired others to share! I always thought I was the 'wierdo' (like my dad) who didn't like sharing from her plate.
I will admit, that I let my boyfriend steal a french fry or two now that we've been d@ting so long, and he always says "I"m SAVING YOUR LIFE! This fry is poison!" as he eats it. I usually steal a soda from his stash later and say "Its POISON! I do this because I LOVE you!"
(Tho I can't do that as much since the doctor figured out caffeine is one of my migraine triggers.

Stupid caffeine...)
My 'MIL' is the notorious one. Like I said before, she doesn't really care or think about about other people's feelings (she's pretty self-centered), and that extends to the dinner table.
We'd all gone out to eat, the BF, his brother, the MIL and Grandma. We were at a small Italian Bistro, and they all ordered family style - but they all ordered dishes with meat or shrimp in them. I don't eat meat and I'm allergic to shrimp, so I said to everyone "ok, I suppose then I'll just order some brushetta and minestrone for myself since I can't eat any of that" and then I did. Everyone at the table heard me say this, and my boyfriend even apologized, because he didn't realize I'd been 'left out' of their choices. They were all looking at me and it *seemed* like they'd all heard this exchange and understood it...
Even though I requested it come as my meal, they brought my soup and brushetta out early, like an appetizer. I wasn't too bothered, and was going to let it sit until their food arrived, but they all assured me it was okay. Even Grandma "oh no, don't let it get cold on our account..."
Well, I load up some bread with tomatoes and am taking a bite when like a flash, MIL loads up the biggest piece of bread with HALF OF THE TOMATOES and says "OH I LOVE BROO-SHEDDA!" (adding insult to injury because we'd all just had a small chat where I was teaching them the proper Italian pronunciations of the foods we were going to be eating...)
I was so taken aback, because it was clearly decided at the table that I was eating something separate. The boyfriend actually spoke up first...
BF: MOM! What are you DOING?
MIL: What? I'm eating.
BF: No. That is Sue's DINNER.
MIL: And more is coming, gosh...
BF: NO MOM. She can't have our food, you're being rude!
MIL: OH. *looks miffed* Well I didn't know!!
We sit in silence for a bit and I decide to start in on my soup, so I move the brushetta to the side a bit........
.....and SHE AGAIN REACHES FOR MY FOOD! This time BF's Brother said something and stopped her (I didn't even realize she was doing it-she had the spoon in the tomatoes and was reaching for bread...)
BF's Brother: MOM! SERIOUSLY!
MIL: WHAT?!
BF's Brother: THAT. IS. SUE'S. DINNER. STOP IT!
MIL: This is the appetizer!
BF: NO ITS NOT MOM!
MIL: Why are you two yelling at me??
BF: You can't just eat Sue's food mom. This is ALL she has.
MIL: Isn't she going to eat dinner?
BF's Brother: THIS IS HER DINNER!!!
MIL: *her eyes widen and it FINALLY dawns on her* OH! I didn't know!
I am sitting there staring at my soup like I wish it would envelope me, when Grandma pipes up:
Grandma: SUE! Aren't you going to share the soup?!
Insert the entire exchange all over again. This time with Grandma.
Then dinner arrives and Grandma offers me some of her Italian sausage about 5 times. I politely decline it and finally say "Grandma, I'm sorry, but I don't eat meat. But thank you for the offer."
Then MIL pipes up:
"Then why did you order all this meat with us?"
BF: MOM! She didn't! She is only having soup and the appetizer.
MIL: OH! Was that your DINNER?! That's not enough food!

*sigh* And THAT is what its like to eat with my MIL in a restaurant.
I now try to order things that I know she doesn't like, or I get just a soup or salad so its hard to 'share' my food, because other wise, she really does keep this up. The BF's brother took the one time to catch on, my BF caught on real quick....and even Grandma gets it *most* of the time. But MIL can't seem to grasp the concept that she is not welcome to my food.
*sigh*
