I can’t tell if you’re joking but people do that all the time, every day. It might be alcohol, strippers, or just random stuff they don’t really need.

If this sounds surprising to you then probably you have enough money that you don’t need to give all of it away to be less sad.

Eventually yes. Just comes to degree. But I do very often spend money to feel that little bit sad. Be it food or snacks or some mostly useless junk I think I need.

When you put it like that it doesn't sound like the worst idea.

If you think about it, the only reason we ever spend money, is to feel a little bit less sad.
