I remember having a conversation with a friend who'd just gotten her first academic job last year, and I remember her mentioning that it felt so lonely! And for some reason, I kind of glossed over that comment at the time. "I make friends easily, I'll be fine!", I thought. But something to consider is that when you've been a student for like... 24 years, you get used to making friends in an environment that's freaking conducive to making friends! You're put in a cohort with people from a similar age group, who study the same thing, and therefore have similar-ish interests. In the real world (not the fairy tale-school fiction version of life), that is not the case!
