I was locked out of the building and my girlfriend slept through it. I'm disappointed.
What methods did you use to contact her?
She should have heard me yelling and knocking
It is understandable being upset that your girlfriend could not let you in the building. It is one of those things where she is not at fault, it is just an unfortunate situation.
When I get home, I'm breaking up with her.
Your frustration is understandable and perhaps you and your girlfriend need to have a sit down about why she sleeps so heavily. I'm not joking, that's disturbing. Being left out in the cold isn't kind.
