<human>: Can you summarize the given text in a few sentences?

My mother is a bit paranoid and insists that I escort my sister to the airport everytime she needs to fly out (we always take cabs because we live away from home and I don't own a car), despite her being in college already.

I decide to take the opportunity to get into work early today, so I take my work stuff with me. Since my sister has 2 pieces of luggage and I offer to lug the heavier one around, I try to be efficient by temporarily storing my own bag inside my sister's large suitcase.

When we get to the airport, we have a few minutes to spare, so my sister takes the opportunity to go to the bathroom and takes her suitcases with her because she forgot which one had her toiletries. I hear the initial boarding call for my sister's flight and think "well I hope she doesn't panic and trip on the way back here" (if anyone is familiar with how inefficient some airports are, the initial boarding call is usually 30 minutes from when you actually get to start boarding). Well, lo and behold my sister really did panic, but even moreso by going straight to her gate without saying goodbye, and forgetting that my bag was in her suitcase. I figured this out after 15 minutes of waiting like a dumbass. I was about to call her, but then I remembered that my phone was also in my bag.

I was able to call my mother on a payphone to airfreight my bag to me as soon as she met my sister at the airport. Luckily it's only an hour flight, with flights every other hour.
<bot>: I left my work stuff in my sister's suitcase, she forgets it's there and boards her flight after going to the bathroom.
