She runs to the bathroom

She decided to run to the bathroom. Her cell phone was in her purse, which hung on the rack, she could lock the door to keep whatever that was out, and call for help. And the bathroom was only 5 feet away, while the front door was over 20 feet further.

She counted to herself 1,2... 3!

Melissa jumped up and ran into the bathroom and slammed and locked the door.

She made it!!

Sighing in relief, she walked to the rack to get her phone from her purse... then she heard her cell phone ring... from out in the office!!!

Oh Shit! She forgot that her sister called her earlier and she left the phone on her desk! Now what?
