I've spent most of the day snowballing with my kid (don't worry, just me, him and the wife, there was nobody around us). I have completely screwed my elbow now as I was throwing so hard. Never seen my son so happy, all he wanted during this lockdown was one snow day and he finally got his wish!
He definitely tougher than I was at that age. I'd go out to play for 20 mins and would have cold hands and feet then want to go back inside. But he just kept going and going. He got me right in the face and knocked my glasses off!
