Hanging your arm out of the car window on a late spring drive at 65mph.
Listening to a cricket as the sun sets on a summer day
Hugs from a good friend.
A warm towel fresh from the dryer.
Your child hitting a double.
An ice cold beer on a hot summer night.
Speeding up so that the tailgater can't get around you.
A long, hot shower on a cold winter moring.
A single cigarette after work with your best friend.
The fact that you can always go to your parents' house for a nice home cooked meal. (submitted by Megan B.)
Crawling under the sheets when they're still cold. (submitted by Jody J.)
