"Look, I get it. You two want to spend some time together. I can respect that. However, Ben is my friend. We have wanted to hangout like this for years. The fact you are sucking his cock shouldn't take that away from us."

-Alright, fine. But you better not be a whiny bitch when you see us kiss. An you better not put us in any awkwardness.

@Everyone just calm down. Look, bud. We're friends. Even more so after last night. You gave me one of the most thoughtful and meaningful gifts I have ever received. I absolutely love it. Now lets all get a long and have a fun time.

@But I do need to warn you. An I know this is awkward and difficult. But Im not like you. I can't handle sharing things I care about. Do keep your hands off and eyes off my girl. For me jealousy goes closer to anger.

"I get it."

@Great. Then lets go, Im starving and breakfast sounds great.
