My Son Sux...

Sometimes I hate being a parent.
I know that is an honest statement and as a good parent I should never ever utter those words... He is turning out to be a lot harder to raise than I ever imagined possible. He is being obstinate, unruly and generally unpleasant to be around. I know, I know he is just being a teenager. He mouthed off to his teacher (in a class he's failing) in front of my husband this morning. He is so very lucky they were in public because my husband was ready to beat his ass right there! Looks like he may be repeating the 7th grade *heavy sigh* so that would me he repeats the 6 & the 7th! 5 years in middle school because he is a lazy S.O.B.!
He is taller than me and now sports a mustache, yeah that will go over well (if) when he graduates @20!
I am looking in to military schools for him, looks like that might just be what he needs...
UGH!POO! SIGH!!!
For all you parents out there, I have taken extra steps with my kids to teach them that they mean the world to me but they mean nothing to the world... Their shit does in fact stink and no one owes them a thing. If they want anything they are going to have to work really hard for it like we did. So please don't think the kids are spoiled. They are "almost" always respectful of their elders and peers (I say almost because of this morning's incident). They are usually fun to be around, but I am starting to think I need to change strategy with him. He is turning in to someone I really don't care for.
HELP!!!
