you can pick your friends...

but not your family.
older brother D's siblings started their families well before we were even married so C is the youngest of the grandkids by about 6 years. The 2 boys are closest in age and Z quickly stepped into a surrogate older brother routine with C whenever they were together. C worships the ground Z walks on to the point that when Z left poor C would cry buckets of tears, not so much any longer. Whenever Z visited the boys would spend most of their time together either at our house or MIL's they were inseparable.
Z has hit the surly teen years, his parents divorced, they have always moved around a bunch and quite frankly he is jealous of C. Yes C is an only child he is spoiled not in a bad way but let's face it when you only have 1 they do get a whole lotta of attention...Plus MIL likes to spoil her grandkids C lives here and sees her weekly and he is still a kid he still plays with toys so yes the woman does spoil him. It's not like she does not spend $$ on the others each time Z & his sister are in town she takes them clothes shopping, gives them cash and so on. They are not deprived, neglected or ignored.
Anywho at Thanksgiving C had just had his tonsils out so again yes he was getting extra attention but by the end of their time here Z was just been ugly with C -it was just sibling sort of ugly, calling names & busting toys but C does not have a sib he doesn't quite understanding how annoying they can be-or so I've heard...
Long story short-I know I know toooooo late for that-found out Z was coming in with his dad around the 4th I asked C if he was excited to see Z and got "no not really he's just mean to me"
I hate to hear that. I know I can't force them to like each other or hang out but I do hope the boys come through to the other side and become friends again.
