I feel for all these girls whose parents can't figure out when to use:

There, their, they're
Your, you're
Than, then

These threads are hysterical. Hopefully you're as passionate about your daughters' educations as you are about living through their lacrosse exploits. Then maybe they'll succeed in life rather than be known only for what they did on the lax field. There is nothing wrong with their wanting to be great at lax, but remember they're kids. Let them have fun and please, for our future, teach them how to use words in the proper way.
