Nah, I can't suggest that for the kid - that's just telling them to pretend they aren't who the think they are.Awkward one alright.
I suppose if they are 15 you can have a chat with them and explain what could happen and leave them then decide for themselves what they want to do (and have a ready made excuse for ref if they want, I couldn't find them this morning etc).
It would be like asking the kid to hide it. Thin end of a wedge, not to long ago gays had to hide their sexuality.
I going to suggest leaving it up to the kid with the full support of maybe half the club.....?????
