it doesn't really send what you send it just shows it to them, they get the option to make an offer for what you send. when they make an offer you will get a message with the offer and will be able to accept or decline the trade. If you decline the guardian you sent will be mailed directly back to you. If you accept then your sent guardian will be mailed to them and their offer will be mailed to you.
