Toe the line

Respect boundaries, that's it. If you know that someone you like doesn't like you, no matter what their reason, don't pester them. If your best mate doesn't want a hug that day, don't continuously ask for one or ask why they are being "moody". And I don't know how many times I have to say this you makes, if a girl doesnt want to talk to you or be near you then don't ask her if she is on her period, it's the last thing you will ever do. 

Luckily I don't have to kick my mates arses into shape over issues to do with me because they are decent people and they know I will stab them but when trying to sort things out with each other, they don't do it in the best way. 

Telling a girl two years younger than you that you cut because of how she makes you feel isn't a good thing and WILL NOT  impress her. And saying that you feel bad for telling her doesn't help either, after that you don't get the right to say anything.
