DS is 17 and has become incredibly moody over the past year or two... He used to be such a sweet little boy, some people even called him a "mama's boy." It's been tough around the house lately because DH is gone often for saxophone concerts and tours. I'm used to giving my DS a good-bye kiss on the cheek before he goes to school, but lately he's been all grumpy and even swore at me! Am I in the wrong here?
