I bought my first house a year ago. Since moving out of my parents' house (in Seattle) I've moved around a lot and never really gotten to know my neighbors but I would like to now that I feel like I'll be in one place for a while. I'm not very outgoing so didn't feel comfortable just knocking on my neighbors' doors to introduce myself, but I don't think that would be weird (I certainly wouldn't have minded if someone did that to me). I did meet a few neighbors organically once the weather warmed up and people were out in their yards more, and other random things like a shared fence falling over or a dog escaping into our yard. Whenever that happens I try to remember to ask to exchange numbers. It's a slow process but it's nice to not feel anonymous in your own neighborhood.
