I told my kids that the video game Minecraft is just like Lego. "Why don't you play with Lego and be creative?" old-man dad said to his screen-watching offspring the other day. (They were on a break from their virtual school homework ... because I'm a good parent)
"This isn't as messy as Lego," one of my kids answered, "and you can't step on a piece of Minecraft and swear," said the other.
Good point. Play on.
