Today i was meeting with a small group of fellow students for lunch, and afterwards go to classes for university, which meant walking on the sidewalk for quite some time. So there were 3 girls and me, but i somehow didnt walk next to them but mostly walked in front of them. I now think it might have given a bad impression of me, and i should have tried to join their conversation, or see if i can talk to one of them. On the one hand i feel like this was a selfish act of withdrawing myself and not trying to be with them, on the other hand they also would speak to each other and maybe 4 people walking next to each other would be too much. Still i am afraid this might have been considered awkward or rude.
