I attended co-ed schools and colleges in my youth and to me being segregated is not the way to do things. However I tend to agree with what Sinsull said earlier in this thread. Like it or not, that's what these parents paid for and expect to get. The gym sessions should have been explained to them though before they paid their money. Couldn't they find somewhere for the little boys to do gym at 5pm and then, as the school has offered, let the others use the school gym after 6.30pm.
