i don't mean this as a snarky reply, but i'll assume you don't have kids?
3, 6, or even 12 months can easily slip by between seeing some of my best friends who live in the same region. while i'm an introvert, i deeply value the time I spend with my friends. i put a good amount of energy into balancing work and family, with whatever is leftover usually being "me time" (reading, learning, building). I try and weave "friend time" into one of the former, but it usually takes more conscious effort than i can spare.
