hiya ggg, arn't teenagers a bunch of b*stards?
.
i have been exactly where you are - in fact i phoned SS and begged them to come and take mine away
they told me to sod off!
only thing i can advise is this - they want you earlier than you want them for anything. they want money alt he time for stuff at this age. so you have the control.
i did take to saying directly to him " i have £5.63 in my purse and i need it for parking tomorrow, i have 3 ciggies, and i WILL break your legs if anything is missing ARE WE CLEAR?" and doing something similar every evening.
once he nicked my last fag. i can honestly say i hated him for a time.
i used to ground him for one month. for being stoned. andything else he was my bitch "make me brew" "go to the shop" tidy the living room!" " clean my car....
now hes lovely. thats becuase he has a girlfriend.
this weekend he wants to go to a party. i and going to buy him a small bottle of voddie and some coke. i am dropping him off at this party and i am picking him up.
this way i know the amt of alchohol he is consuming ( he is also sharing it with his friends) i know where he is all the time. which is much better IMO than him going out getting pissed and falling asleep on the pavement and getting a good kicking from some fella.
for the voddie - he is cleaning my car -inside and out - i bought car cleaning stuff especially! 
things willget better xxxx
