On a related note, this thread reminds me of a conversation with my SO recently.
Kaypeep: Honey, what kind of cake do you want for your birthday?
Kaypeep: What kind of pie?
Kaypeep, that is hilarious and sounds like something I would say!
Then I'd be all unpopular because I usually like black olives (in addition to other stuff) on it and practically no one I meet ever likes black olives on pizza.
Also, some of those apple pizzas are awesome. I even had a great chocolate chip/rocky road-ish pizza once, fresh from the oven too... so gooood.
In regards to the allergy comments; I agree that allergies should be considered, but in this case, Jackie just hates chocolate, no allergies. I'm sorry, I meant to include that in the OP. Jackie actually doesn't eat many sweets, so it's beyond me why she even made this offer, other than she must be having her biannual cake craving or something.
Adam generally makes his own cake, from a box mix. It's usually chocolate. He didn't this year because of Jackie; he felt having two regular sized cakes in the house at the same time would be too much. He initially thought she was going to make a box mix for him, so he was going to rattle off a few flavors he liked, some of which Jackie also likes, so this way would have worked out much better, but Jackie didn't want to make one, she wanted to buy one premade from the grocery, so that limited the options significantly. She is capable of baking a box mix, but I think she simply wanted the convenience of a premade cake, which apparently was still too much of a hassle for her in the end.
Adam's a bit put out about how everything went down, but the consensus here made him feel a bit better than he wasn't being unreasonable and Jackie was making it about herself. Lately Adam's been realizing that he has been more generous with Jackie than vice versa and this is just another instance on the pile.
