I've been going to the gym for a little while now. Everyday that it's open, I'm there. (That is everyday that isn't Sunday, or everyday that the gym isn't flooded.)
The Kiddo has asked me a couple times if he could go with me and I keep telling him no. I have told him though that when he gets bigger he can go to the gym.
Well, last night he was laying on the sofa and I came to sit down. I picked up his legs and laid them across my lap and told him how big he was.
I went on to explain to him how he used to be little and he got bigger and bigger and bigger and now he's so big.
My Kid, having the excellent memory that he does said "Yea! Now I can go to the gym!"
Not quite, Kiddo. Give it a few years.
