This has largely been my experience as well but in the US. However, a new couple moved in next door to my apartment. We’ve done happy hour with them and I share the fruits of my cooking/baking adventures. Stop and chat when we are not in a hurry. For whatever reason we’ve not gotten to be much closer than friendly neighbors. Could be the woes of young professionals in their 30s without kids but the effort definitely feels greater than at other points of life.
