We had egg on our house once. Had to paint the whole darn house. (it needed repainting anyway.) I would make your teen paint the house. At least the front anyway. Maybe if the friends see this they will fess up and pitch in? Maybe I'm dreaming?
When I was a teenager we toilet papered the crap out of a friends 2 story house. He got grounded and we all felt so bad that we went back to clean it up.
Totally off topic... but since you mentioned being Jewish and since it's Passover... do you keep kosher for Passover? This has nothing to do with eggs on houses... I'm just feeling a little guilty that I had a regular bagel today...Actually my little one said the funniest thing today(I had to laugh...).....shes like ...IS this what the Easter bunny brings us Jewish people?...ROFLMAO..OMG......OY!
