To that lady who slammed her purse down next to me
Maybe you were in a bad mood. Maybe you have an exam for that scary looking genetics textbook you were reading.
Either way, though, be aware of where your stuff lands and be aware of the amount of space you take up. I like to be as close to the edge as possible. I consider the dividing line between the seats a good division of personal space. Just because your purse is huge doesn't mean you should slap it down so it takes up the rest of the seat and have your coat land on me as well.
And try not to roll your eyes when people ask to get up. You're in the aisle. It happens.

So did you let THIS LADY know
