1) Standing up on the bench seat beside my Dad so I could see over the dash board as he drove around listening to country music with his flask or beer can in his hand. I loved the '50's.
2) Discretely opening my presents under the Xmas tree early to see what I was getting and then carefully wrapping them back up. And then feigning surprise on Xmas Day.
3) Playing wiffle ball in the yard with my buddies. (Except for the time I outlined the batters box and foul lines using detergent. Killed the grass. Mom didn't much like that.).
4) First crush on a girl. Being "in love" for the first time is great until, of course, she rejects you. Crushing the first time, but after that, you get used to it.
