Homeless?

So, I sit outside a subway, sandwich in hand, book in lap, foot jittering, waiting for my mom to pick me up. A mother and her two daughters, one like 3 and one maybe 10? walk past me. The younger daughter tugs on her mom's shirt and points at me, whispering really loudly "Mommy, is that girl homeless?" I sort of put my hand on my face, and her mom says really loudly, "NO. She is probably just waiting for a ride." She turned to me and said "Pardon my daughter, she is really young." To which I replied, "No, it's ok. I need to shower anyway. Guess my hair is greasier than I thought."
