Judging by OP's other posts and threads about her DD, I don't actually think she's doing either. What's very likely happened is the poor girl has asked, OP has said no (a quid for makeup remover?! Horror! Sharing some of her chocolate?! Never!), and her DD has pushed back. Likely tried to explain to OP that her friends get these things, maybe got stroppy as 14 year olds do...because why wouldn't she?
Can easily imagine it to have gone as this;
DD: Mum, can I have a piece of your chocolate?
OP: No, you finished yours. This is mine.
DD: But I'm on my period!
OP: So? I don't need chocolate on my period.
DD: That's not fair! I just wanted some of your chocolate. God, my friends parents pamper them and all sorts when they're on.
OP: <Immediately takes to MN in another miserly rant about her teenage DD>
I'd be hurt if DH wouldn't give me a couple of pieces of his chocolate, just because I finished mine over a month ago. Especially when I was in discomfort.
OP just comes across as tight fisted.
