We are very similar. I started taking my daughter to Fulham at the age of about 4 and got a ST for both of us a couple of years later which we've had ever since. Her attendance has dropped to a couple of games / season & I'm wondering what to do when she goes to University.
I was 45 when we had our daughter, so I was always one of the older dads in the playground, although it is becoming more common now. But it never really bothered me because I enjoyed doing active things with her - playing football, cricket, Frisbee, stuff like that and taking her to Fulham...
