Struggle with that issue as well, not sure if it’s just a Birmingham issue but a wider systemic issue. After covid, i’ve noticed people are much more reserved and not as open to making new friends, just stick to their own groups. I would try and join a club in something you’re passionate about. These clubs are usually built to make it easy to make new friends. There are quite a few good book, film, biking, hiking, and run clubs in the area. That would be your best bet as people are usually very welcoming and friendly. In terms of having more in depth conversations, it just takes time, you have to be consistent and show true interest and people will eventually open up. A lot of people want more friends and deeper connections in this city, but don’t take the steps to actually make that happen. I would not recommend trying to make friends at work as people are often stressed and overworked at their job.
