Being an adult

I don’t know what definition for being an adult is, but to judge on peoples’ comments when I am behaving (according to them) childishly, it is boring.

During my vacation last week we played a lot of Monopoly, and when my son landed on one of my streets with 4 houses on it, I was celebrating his economic ruin with wild dancing. My 8 year old son started crying and refused to continue the game. “For heaven’s sake wife, can’t you act in an adult way?” my husband complained. Is celebrating a financial success, even with just paper money, forbidden after turning 18?

The other day I was in my village pharmacy, and just before entering I was thinking about something funny and couldn’t stop laughing, not even when it was my turn at the counter. The pharmacist said to me: “It is not fair to laugh if you don’t tell what you are laughing at.” And I am childish, how old is she, 4??? And is spontaneous laughing forbidden after turning 18?

Is scaring the hell out of the kids (turning all the lights off and take a sheet on my head), being the (unofficial) village champion on building sand castles or breaking the kids bones on the trampoline childish? If it is, I prefer that than being a boring adult.
