Ummm my advice would be to send it, but think about what you write. Make her pairents proud that she is with a nice guy like you. The pairents that would make a fuss over the letter are the kind of pairents that would worry about the kind of person they might be dating if they suspect something. Use the letter to hint to them that your a nice guy and the pairents might respect you. They might even invite you round from dinner. And from what Ive seen, people that see eachothers pairents become a more stable relationship.
