MY teen is exactly the same! I want him to get his full licence asap (I'm sure it'll work out better for our insurance) and to get that, whilst he needs to be 19 and held P's for a minimum of 2 years, 6 months of that needs to be on P2's and that clock is running out!!
I have lost count of the times I have offered to pay / go with him / vaguely imply him that his friend will get his full licence first...you name it: no go!
It wasn't this hard to get him to get his L's OR his P1!
And they say having littlies is challenging! Pfft!
