I moved here before I met my husband. But man, if I had to depend on him for friendship, I'd have two friends only and I'd never even see them. He's a very introverted soul and is quite happy being by himself. (His one brother is the same and he has a very quiet and reserved and introverted girlfriend). I am also introverted and prefer my own energy ,but I am a bit more on the extroversion scale than he is. 80% of the time, my own company is good, but 20% of the time, I need to be with other people.
I am a ametuer musician (though sometimes I get paid, shock horror!

) and play trombone in five different bands. I went along to the first band because there was an advert in the local paper looking for trombone players. I joined the band. Musical network grew and they say, hey come along to this one too. Soon found the musicians on Facebook and friended them. Found more bands. Same. Musical network grows and grows. Soon you start organising nights out and activities unrelated to rehearsals and gigs. Boom, friendships.
I joined an allotment that was starting up. You dig, you laugh, you grow veg, you share tips. You create a facebook group. Boom, friendships.
I have a few friends that I know directly from work, that usually become friendships with organised (well in advance, lol) nights out.
Some folks think social media ruins true friendships, but for me, it's our easiest way to get in touch, chat, and organise days or nights out.
