If you are looking for a way to meet your neighbours, I suggest simply getting pregnant, taking your year of maternity leave and walking up and down the street with your baby on a daily basis.
I have met more of my neighbours in the nine short months my son has been around than I did in the eight previous years.
While I have always said hello to my neighbours, most of whom live in the city and only come up on weekends, holidays and summer vacation, when you are pushing a baby stroller, people will come right up to you and stop and chat.
It has been wonderful.
I have met so many interesting people including one woman who has been coming to this neighbourhood since she was a girl in the 1940s. PG has three daughters and in the wonderful small world that we live in, I actually worked with one of her girls. I had never met L, who worked at my parent company, but we chatted on the phone a fair bit, and I finally got to meet her this summer when she popped to say hello.
So to recap: Baby equals great opportunities to meet new people.
