There were 3 benches in the lobby of a 27 story apartment building. I was sitting there for 10 minutes waiting for delivery after 5 minutes there was 1 young girl sitting in the bench on the left to me, then 2 minutes later another sitting on the right bench, the weather was cold so no reason for them to want to sit here. Was it a sign they wanted me to approach them or was it a coincidence? I have approach anxiety, they look 10 years younger than me, would it be creepy to approach them?
