We had this discussion with ds2 (14) last night - he is a keen cricketer and plays for a local team - well, the most local team there is, which is actually a good 20 minute drive away.
He is currently playing for the U15s and they want him to play for the 3rd Eleven too - but that would mean practices on Tuesday and Wednesday (6.30 - 8.30), and matches on Friday evening and all day Sunday.
Dh and I think that this is not reasonable, for several reasons. Firstly, it is taking up a lot of his weekday evenings, and as he is doing his Standards courses, we are worried about him committing so much time elsewhere.
Secondly, it means a whole lot of chauffeuring for dh and I, and buggers up three evenings a week (plus making it harder to work in any activities the other two dses want to do).
Thirdly, he would have to drop out of the school musical, because the wednesday and friday rehearsals obviously clash with cricket practice and matches.
Fourthly he already has a morning paper round and an afternoon one, and is going to be knackered if we add in even more cricket.
And finally, it means that three days a week he has to grab a quick snack before cricket, and then have his dinner microwaved when he gets home, which will mean him eating too late, in my opinion - unless I only cook things on those days that he can have before cricket (which will be too early, I think) and that can them be reheated for the rest of us.
But he loves cricket, and is desperate to play more - am I being mean and unreasonable not to let him?
