The Fun Stuff

Random thing about you?  I am a full-time Volleyball Mom. 

Perfect Saturday? Sun, food, a body of water, and friends and/or family.

Funny family memory? I pranked my entire family by falling over the car seat of a newborn family member fresh out of the hospital. (No baby was injured — we removed them from the car seat before walking into the house!)
