Why do we behave like this?

Memorial Day weekend...woo hoo! I love everything about it...warm weather, parades, bbq's, etc! We're going to our local parade on Saturday morning...Bailey's 1st...can't wait! Ever notice when you see your friends, family & neighbors in a local parade, all of a sudden it's like you haven't seen them in 10 years, and you are sooo excited to see them! You start cheering and hootin' & hollerin' like they're bigger stars than Brat Pitt! Why do we behave like this?? Too funny!!! I admit it, I do it! I wave and yell their names...crazy...when what I should say is, "See you back in the neighborhood in about 20 min!" I found the most adorable pair of red, white & blue plaid capris for Bailey and Brady's flag t-shirt is ready to go...plus, tons of flags for waving! We're ready...and yes, that will be me dancing to all the passing marching bands...John's lucky, isn't he?
