My point is that if someone isn't doing something things alone, they don't necessarily feel awkward, they could have other reasons to not go, and saying "but I have no-one to go with" may just be a socially acceptable excuse that they use to hide the real reason they don't want to go.
Your point is not related to the subject at all. What do you not understand? The person in the screenshot does not address you or your like, they address specifically people not going places alone for fear of people looking odd at them, even though nobody cares.
