As a child, when we were on the outs we gave personal possessions away (gave my sister my music stand, got my grandpa's bolo tie from my dad), gave time/talents to each other away (i.e. I'll spend a week teaching you swimming) or made things. Stuff like that. It's not the gift but the thought, but I'm sure you know that.
Being told you're delusional does not necessarily mean you're mental.
