Thank so much everyone for your thoughts on this. It means a lot to me.
I do, of course, cook and offer whatever I have. I really have no issue with that at all. I made and served my mom a cake (she's diabetic and dearly misses sweets) this afternoon. She loved and appreciated it.
I really, really don't know why it bothers me...

I feel stupid for asking about something so minor...Jeez. I could smack myself upside the head....
Perhaps I simply want the courtesy of "is it okay if I fix myself something?".
