Irish,

If at all possible, sit where you CAN'T see them without making a neck craning spectacle of yourself.

Also, how much longer is she going to stay interested in these games just to please XH? When S involved doesn't have anything to do with her?

Remember why you are there. Your son, no one else. No hidden agenda on your part. You can be proud, so enjoy these games like you really do, and when your son looks up in the stands, let him see his Mom beaming at him. ((Hugs))
