No, I'm not talking about how terrible it is to love a puppy. I have a hard time visiting the kennel or pet store with my boys and not coming home with a new pup. I fall for them quickly, especially those who can keep up with my 20 month old.
However, about 2 hours later, I've forgotten about that pup. My 'puppy love' was, truly, ephemeral.
Most of us have had similarly powerful feelings of adoration followed shortly thereafter with near amnesia. The problem in human relationsips are that these feelings, if they do not mature, can get you into a whole host of problems.
I recently read a great quote on puppy love:
"Puppy love with a short leash on courtship can lead to a dog's life."
A long term relationship requires a great deal of commitment, patience, friendship, interest, and love. Puppy love might get you going but it sure won't help you last.
