It’s great to make friends out of total strangers.
The downside is minimal. You have next to nothing to lose if your acquaintance doesn’t work out — you don’t have to see each other, and since most acquaintance will be left quite amicably, there doesn’t have to be any awkwardness should you meet in another circumstance.
The upside is tremendous. You get to know someone from outside of your clique, and I you will open yourself up to something much more different: topics outside of your knowledge base, a lifestyle that you don’t feel 100% comfortable with, or a fresh pair of eyes that take a good look of everything you are and everything you do.
I hope I get better at this.
