My girl is 5. She has taught me the meaning of life.
My ex wife is 31 and she has taught me "selective hearing".
My plants vary in age and they have taught me patience.
Isn't it funny, husbands learn selective hearing from their wives. Wives learn it from their children! LOL
Oh yeah, last but not least, my dog, a pomeranian bitch, she has taught me that begging does get you your way, eventually. Peace!
