I agree with pp's: it's how your Dh told him, that was too harsh.
But like posters said, you don't want to crush children's dreams, but you also need to be realistic and truthful: I agree with the posters who said that A level students appreciate honesty that they aren't going to get an A, but might/can strive for a B.
You can't have all these kids thinking that realistically they are going to make it as professional footballers or you tubers.
They need to just enjoy doing singing/football/rugby/gymnastics for the enjoyment. Of now. Enjoying it fur what it is, right now, rather than thinking it's going to take them somewhere.

And the poster who said their life is strict, regimented, the club need to know where they are every second, for possible drug test, is spot on. No.... going to a family party, or having a beer with your mates. Because it's already been calculated that you only need 0.74 of protein, from chicken today, to meet nutritional ......
No one dreams of being a team manager, IT support desk? Well they probably should!!
It's all a question of balance.
