Invalid Sounded like a good trade at the time

So I wanted to trade with someone who's name was a heart, then after the trade he changed it to infected^. Here is the entire chat from him, luckily for me I decided to do a half and half trade to make sure i did not lose anything and I find it quite funny that I did not see this coming since I was willing to offer three keys.
