GGgrrrrrrr ANGRY

I am so annoyed!!!
Last year when the twins were at school - I didn't appreciate how smooth things ran.  I moaned and prodded and got frustrated when they didn't take their GCSE's seriously enough (especially Connor) and had to remind them to do what little jobs they had to do and so forth....Connor messed up his GCSE's because Skating was too high on his priorities.  Lissa did really well and I was very proud of the hard work she had put in.
Now...they are at college and its pretty awful!! Its supposed to be a time where they are growing up and being more responsible...actually Connor has grown up a lot and is being more responsible but his life is fairly easy - the college course he is doing isn't too taxing and the rest of the time its SKATING, SKATING, SKATING he is obsessed!!
Lissa - already got thrown off one of her courses and I get letters on a weekly basis about the other courses she is doing - for not turning up or not handing work in.  She is costing me a fortune in travel...she always seems to have money left on her Oyster card however to travel at the weekends and today I get a letter from South West Trains saying that in February she was caught on a train having not paid (I PAID HOWEVER!!!!!) and now they want £50!!!!! I think it would have been £20 if she had told me and it had been paid by now - but now there is an admin fee too so its £50!!!

If anyone can think of a way that she can pay me back somehow I would be most grateful...
