This sounds abusive to me.

I think your mother was taking out her insecurities on you.

Why should not a fifteen year old girl have a stuffed pepper?

That hostess was so sweet---taking you into consideration. You were a guest, just like your mother. And 15, to me, is an adult.

You deserved good treatment and that hostess was doing that by feeling for you. Your mother was emotionally upset and taking that out on you.

I am sharing this because my aunt did things like this to me, too.

Also, I believe these spontaneous thoughts may be (maybe not) because your mind is simply processing what happened to you.
