Sometimes a few of my closest friends introduces me to their other friends that I haven’t met yet and sometimes it often starts off quite awkward. Just 2 days ago, my friend and I meet up at a park, and yes she brought a long a few of her friends that I never met before. And I started saying “hello, nice to meet you” but when it comes to hand shaking or any forms of hand gestures use for greetings, it often ends up terrible or weird. I mean, when I hand shake, I usually do it quicker because I have this feeling that I dont have to hold on much longer, and sometimes they become shocked because they thought I had a weird touching disorder or something, sometimes I can even become hesitant and often leaves the person hanging without receiving any hand shakes or high fives or whatever. What do I do to end this awkwardness?
