Playtime is when time goes by too fast to notice the sun going down. Whether that is reading, skipping, bicycling, playing an instrument, playing LEGO, it’s all playtime if it doesn’t feel like work. As a child you have no concept of what cleaning the house is really like, so you play house and clean up and make dinner, it’s only as an adult that “playing house” is a lot of work and it’s not playing anymore.
I play video games and the guitar, my guitar teacher told me video games are good for dexterity….I don’t think he was expecting me to get better at Guitar Hero than the actual guitar. Whoops!
