First impressions can sometimes be a make or break situation for what comes afterwards when the first initial interaction has passed. I've had a couple of bad first impressions that end up being unjustified when I came to know more of the person, which I think could be a good rule of thumb to not take first impressions too seriously and find a way to work through the initial feelings experienced. Moving forward is a constant practice for people like me who a curious generally about the universe(s) that other people inhabit :)
