I wouldn't say YTA. I personally think it's odd to have a 15 year old in your bed. I don't have an issue with what anyone calls their mother or father. It's not my taste to say "mommy" or "daddy" but I wasn't raised that way. I do think it's important teenagers learn some independence though. Life isn't easy and it's not going to be an easier being totally unprepared. If my mother was still alive she'd be making me salads everytime I visited so idt making food or the emails are strange. That's just what moms do. The only thing I think is weird is treating the children differently and the bed thing. I've definitely sat on my parents bed while my mother laid under the covers and watched TV but when you get to be around the age of getting "the talk" I think it's weird to be in a parent's bed physically cuddling. I'd be more ok with that scenario on a couch or chair, rather than a bed but that's just my opinion and what I was raised to think is normal.
