I got drunk and had sex with friend.

Really? Come on.

"I got drunk had sex with friend. normal day never cross friendship line."

Your saying you got drunk and had sex with your friend. On any other day WHEN YOUR NOT DRUNK you wouldn't cross the friendship line, I.E. wouldn't have sex with him.

So, what do you think. Was it the alcohol, or was it just a special day where you wanted to have sex with a friend?

I'd say it was the alcohol.

i don't know... probably

why don't you try asking yourself?
