Yep, I met my wife at an office party - she didn't work for the company, just stopped by with someone who did

And not just the office friends that come from it -- I spent an hour a day on the bus, grabbed lunch around town, was downtown when work wrapped up and ended up at a nearby bar/restaurant, went to shows because I was downtown, etc.

Just being forced out of the house led to SO MUCH MORE.

Now I work from home and while we do travel a lot, we barely ever leave the house when we're home. We didn't make a single new friend for like 5 years (and we are a VERY social couple, generally the center of most of our friend groups). We've only just now started making new friends again now that our daughter is a toddler and getting us out of the house -- and it is incredibly refreshing
