Hello wannabe adults, how are you managing to keep in touch with old friends? Esp those who have gone very different paths (and cities)

I call them, I create a list of people to call each week, preferably 5 each week, message them that I was remembering them this week, it's been a while let's talk, ping me when you're available and I'll call and then call them at a set time.

I don't leave my friends behind, few of my friends are going through a tough time and I call them frequently to make sure they're doing ok.

Recently one of my friend is going through a divorce and wasn't picking up my phone so I called him using my wife's phone, to tell him that it's ok and that I'm here for you and I'm just one call away.

I don't keep a mental log on who called when and how much. I dont leave my friends/family behind.

I deleted their contacts and saving contacts of only those who are doing call or message on their own

For my childhood friends, we meet on Makar Sakrant festival to fly kites (atleast for us ). For college friends i am not in much touch. Whenever I visit their home town I call them and vice versa
