They're awesome new friends, but also unlikely to be still in Montreal in a couple years. It kinda sucks making connections and having people move away all the time, but i'll enjoy it while it lasts!
I've been feeling this a lot recently. Everyone's gone in their own direction after college - I'm happy for them all, but I already feel nostalgic for times I was having six months ago!
I think in september will come the time to make a decision and start taking steps towards the future.
Best of luck with that; I'm doing a lot of the same searching right now. If you ever need to bounce thoughts off of non-judgmental strangers on the internet, you know where to find us :)
