The quote reflects a sense of frustration with social media, comparing the experience to the anxieties of childhood, specifically the nervousness of being selected for a game. The author seems to imply that social media can often feel exclusionary, evoking feelings similar to those faced during childhood social interactions.

In essence, the author, Katie McGarry in her book "Walk the Edge," suggests that the nature of social media interactions can sometimes lead to feelings of inadequacy and impatience. Rather than being a source of enjoyment, it can evoke nostalgia for simpler times where friendships and connections felt more genuine.
