Not like..born with a twin.. more like... you go to a horse show and say*that horse looks like my horse* that type of twin....
My horse does... this horse belongs to my friend's barn. He has the same markings on one side of his body and the other side is different. He has the same head markings though.
and then I found this picture on CafePress..it looks like my horse so much!
The horse on the card is lighter than my horse's head..but its the same idea..
