I rarely make the effort to reach out to people, which probably makes a lot of people think I don’t care enough about our friendship to be bothered. Most of the time I badly want to talk to someone more, but I avoid reaching out because I worry I’m bothering them.
You can become instantly quieter amongst a crowd. Usually, crowds are not your thing and you can become a bit anxious in them. You would rather stay quiet and in your own head than ever have to make nice small talk with a stranger.
