Were they drunk?

my guess is that some one took the welcome sign soo serious and thought it's welcomed to break in ?

Probably PISS drunk.

I'm glad you capitalized that pun. I don't think anyone would've noticed how witty it was if you hadn't.

No, it's just Florida.

That was my first thought...really drunk, went to the wrong door, struggled to get in because they really had to pee, couldn't hold it anymore so pissed on mat...then realized they were at the wrong door and stumbled off. Only thing that makes me doubt the theory is what I presume was the time of day - who is THAT drunk in the middle of the day?? Either way, f your life OP, and glad you're safe regardless. If it was a real break-in attempt, good thing you were in class.

Probably

Buying a new welcome mat is easier than replacing everything they would have stolen.

Yeah but he was probably still pissed about it

Doesn't change the fact that OP shouldn't need to replace anything, no matter how inexpensive.

Op doesn't actually have, wash the mat and he'll be fine.

They must really not like that mat.

Guess they didn't feel welcome

Or maybe they felt a little to welcome and comfortable.

They left a dent in the door? Wow. At least they didn't get in.

He was trying to use your bathroom.

I imagine it's one of those cartoon dents with the outline of their face as the dent.

While you're buying a new mat it may not be a bad investment to purchase some security cameras as well

Well that may be an option for a reenter or home owner I'm not sure they'd be allowed to put up security cameras on campus propriety. Most universities I know have security in common areas, op should find out though, maybe they caught the culprit on video.

A security camera belonging to a student? College students will steal that shit. In a heartbeat.

if it makes you feel better they probably messed up their shoulder pretty bad if they managed to dent a metal door.

when you gotta go you gotta go
