However, whenever there is a social gathering and such that I have to attend, my default, standard set of activities unless someone approaches me is to just look around look at my surroundings, get lost in my headspace while taking a walk around the place while tuning out others and greeting anyone who I happen to know. If I happen to be interested in having a conversation with someone, I will have it. But I'm simply not interested in people by default, or meeting people for the sake of it.
I have never spontaneously felt any inadequacy with myself when doing this. What inadequacies are there have almost exclusively have been pointed out to me by others, much in the same way the author does with Aditya here. I just don't ever feel a need to talk or force a conversation unless others (relatives and colleagues) are pressuring me to do so.
The mannerisms of the Author are what I've often heard from the management people in the companies that I've worked for and in some Linkedin posts. I'm not trying to deny at all that effective communication and networking has its benefits, but the way they talk, including the Author's article often makes me feel like they're masking an insurmountable amount of annoyance and vitriol for those who just don't want to talk. It's as if they will not accept anything other than the status quo of constant chatter and networking.
