Welcoming Party

I wonder why my son greets his father with such a warm welcome when he comes home from work? He will stop whatever he is doing and starts screeching and jumping (his version) and has a BIG WIDE SMILE on his face. Like yesterday, I came back from the dental office and nary a greeting for me. But his dad goes out for 2 seconds to get something from the garage and he starts crying and he does his welcoming thing again 2 seconds later when he comes back in....WHAT IS WITH THAT!!!!! His dad gloats... Huh...just watch what happens at night when he is ready to go to sleep! That is when he wants his mama. Well..I guess that evens things out. I do have to admit his dad is more fun. Mom is just the maid, feeding, changing, cleaning.
