Why is that drunk people always wanna talk to you...i mean really!

i was on the bus today and this drunk guy is trying to get the attention of ANY one that will talk to him. So my eyes are bopping around the bus, trying to avoid his random blabber. But then he reaches over me to close the window... and this guy stank. I mean burn your nose hair stink!.
so I'm like

"Dude, you cant be shutting the window, when you aint smellin' nice."

and he's all like

"bleeebbbbhhhhhbledooo ( thats not an exaggeration he just rambled)"

so i opened the window again and he just continued to moan and ramble at me till he had my attention.

what i don't understand is why drinking excessively is fun

*note I'm allergic to alcohol so i guess i'll never understand *
but tell me anyway..I'm intrigued to know.
