There are a number of signs that point to getting old(er). Grey hairs, aching joints, wrinkles. Except I don’t have wrinkles because #asiangenes! Greys, definitely. But that’s another story.
A change I didn’t expect is my sudden urge to be friendly. Usually as you get older you become less friendly, or rather, you tolerate less bullshit so basically you cut out the bullshitters ie most of your “friends” during your 20s. And it’s not like I want to be friendly with just anyone, but for the first time in my life, I actually want to be friends with all of my neighbours.
