Yes, they knew because I said it was Taco night. And in the gajillion sleepovers I had as a kid, nobody just ordered food. The parents would always provide a meals/snacks and no one thought to just order food. I guess what gets me mad is at dinner time, food is being delivered to my house in front of other family members (including the one - me - who invited the guest) and nothing was even offered. What if I had ordered takeout for younger DD and myself and did not offer any? BTW, I don't like what they ordered, I think it was the principle of well, thanks for your hospitality, but I am just gonna get my own food and eat it. Again, though, I will just casually talk with DD about it in a few days and explain why I found it rude to see what she says, because for all I know, she was embarrassed by it too, but we are still working on her spine. I have not absolved her or condemned her yet because I have no idea what went into this idea.
