Throwing snow funny or what?

I was ping my neighbors house today , we have three feet of snow ( we rarely have it so it is a novelty) I am in my late thirties and my neighbour saw fit to throw a big snowball and hit me right smack in the face she thought it was funny .I didnt think so what should I do go out tomorrow and throw the biggest one I can make at her would that not be funny as well ? what would you do ?
