I accidentally set a sexually explicit in message meant for my wife to my realtor - we were all standing together so I asked him to just delete the most recent message from me and he did so. I am much more careful now.
If he didn't that's up to him. If he felt embarrassed or uncomfortable by that message after refusing to delete the message that's on him. I don't really give a shit for my feelings - I just didn't want to make him uncomfortable.
