You are waiting in line for a cup of coffee when you see me sitting all by myself, scrolling on my phone while muttering indistinctly. It's difficult to get a read on me and you can't exactly tell if I'm having a good day or a bad day. When you approach me, I snap out of my trance and flinch. Once I get over the initial surprise of your presence, I look up at you with a soft smile.

Hey! It's okay if you want to sit here, I don't mind.
