I wonder which one of you is the “dumb one.” I’m inferring that you needed the spare key because you locked yourself out. I hope you’re the “pretty one” — that’s the more important attribute.

As a proud feminist woman, this offends me

Why wouldn’t you just go to nearby hardware store and have a duplicate made from your key.

A) it might be a “do not duplicate” key which locksmiths aren’t capable of copying
B) it might be because they have to have a locksmith change the lock for safety purposes

Every apartment I had I was able to duplicate the keys. Even at the Walmart kiosk, so this is interesting.

They're still expensive

So is she going to reimburse you for her $50 screw up?

To be fair, women have a large assorment of things in their purses/handbags. Just look at Mary Poppins.

I hope she also found $50 to pay you for her mistake.

Unless Sis is sharing the apartment, why give her a key your apartment? Several FML’s have been written about problems with people showing up and letting themselves in. Even if you trust Sis with your life and possessions - how about her friends, boyfriends, etc.

OP get that key back.

What a ridiculous place to keep a key!
