Final year of my college degree a friend of mine asked if he could stay with me. He had been kicked out of a couple other universities and finally begged his way into one where I was currently living.Told him I didn't want drama or partying in my place.
Guy would routinely show up stoned, started getting his parents to bug me about getting him a loan, general disruptive behavior. Lying, telling my gf (now wife) one thing then telling me something different.
Came to a head when I got a call during a night class, he had come home drunk or stoned or whatever and began telling my gf he was thinking about killing himself. Now when my wife was younger she had attempted suicide so this struck a chord with her. I of course raced home and we took him into a hospital to get him some help. He proceeded to tell the doctors something completely different and was sent home with us.
Kicked him out as soon as he found a new place to stay. Haven't seen or talked to him since.
Doesn't make a mess during consumption? Tell that to my 2 year old...
