Old friends
Do you have any old friends that you haven't seen in a while? Long enough that you've become different people, perhaps your roads have diverged?
I have a friend like that. Someone who seems to fade from my life altogether, and then, suddenly, re-appears at the oddest times. Having a friend that like can be hard. They can remind you of who you once were, and that can be challenging if you are a different person now. But it's good to connect with them. Every friend I've had has been part of making me who I am today. Even if they aren't as close as they once were, we'll always be a part of each other's stories, and that's pretty cool.
