Too Nice For Her Own Good
While the world definitely needs more kindness, being too nice can land you in some uncomfortable situations. This OP’s roomie was supposedly so kind that she ended up bringing a stranger who missed the last bus home and let him sleep on their sofa. If you ask us, that doesn’t sound very safe.
What’s worse is that after her “good deed,” she couldn’t sleep and panicked all night long because you know, what if he turned out to be a psychopath? Well, it’s a little too late for that, don’t you think? Since the OP was around to share this story, we can only assume that nothing bad happened thankfully.
