I know how you feel...it's hard when you are doing it alone too! I have a 16 year old that you described in your 15 year old. He's a good kid, but alot of work to keep on track. The attitude sucks at times too...the mouth is an entirely whole other problem. The 14 year old is tough too!...Whoever said boys were easy???? The 16 year old has a girlfriend and he works part-time. The job can stay if his grades are good. The 14 year old is entering high school and very involved in sports...I hope this encourages him to do well acedemically also. Right now it's like a vacation not having to get everyone up and out in the morning and then help with homework all evening.
I am not ready to step back and feel it's my job to stay on top of them while they are legally my responsibility...and being the codie that I am it will probably last well into their thirties!!!!!!
