I had an encounter with an SS mom yesterday evening. I was meeting up with DH after work for dinner since our power went out and I didn't want to sit my 33 week pregnant self in an unair-conditioned house in the extreme heat the DC area is experiencing (luckily it was back on by the time we went home).
I was in the waiting area of the restaurant entertaining myself on my tablet (which DH had just given me Monday for my birthday), and there were a few people waiting for their pick-up orders (Famous Daves).
A mother (SS) and her son (B), who was probably around 7 I'd guess, sat near me.
I'll paraphrase since I don't recall the conversation exactly, but this is basically what happened:
B: I'm bored!
SS: It'll just be another 10 minutes
B: I'm bored now!
SS: That lady there has a toy - go see if she'll share
B (comes up me): Excuse me! My mom says you should share your toy with me
Me (startled, because I didn't think the mom was talking about me in regards to a toy): Um, no, I'm sorry. This isn't a toy - it's expensive, and I don't let other people use it.
B: You're supposed to share!
SS: Come on! He's bored, and that thing can keep him entertained *Gives significant look to my belly* You'll see soon enough.
SS: Come back over here B, that mean <female dog> isn't nice, and won't share. I feel sorry for her future kid.
Me (probably shouldn't have engaged the crazy, but I'm hormonal): My kid won't be taught to be entitled to other people's possessions and I won't expect the world to entertain her.
SS: <female dog>
Me: Thank you for the compliment
B started throwing a tantrum and SS kept talking about me under her breathe, and then started complaining about me to another woman seated nearby (they didn't seem to be waiting together, she appeared to be a stranger). What boggled my mind is that the other woman agreed that I was selfish and rude to not entertain the kid, and it was my fault he was throwing a tantrum. Luckily, DH arrived shortly after and we were seated.
I wonder what would happen if you turned something like this around on the person saying it to you...
SS:let my child play with your thing, he's bored.
InnocentSubject:I'm sorry that won't be possible, this is my thing, and I'm using it.
SS:Well he's bored, and he wants it.
IS:Fine, but can I have your car keys?
SS:What, why, they are mine.
IS:Well, if your kid is playing with my thing, I'll be bored, and I'll need something to play with. Since it's okay for me to share my thing,
you should share your thing.
SS would hopefully sputter and shut up at the audacity of your request, if not, imagine the fun you could have with the argument.
