Their love is proportionate to how often you're at the meetings and out in field service. I don't do any of that anymore and I never hear from anyone except some elder who would literally call and text me at midnight for some reason. He hasn't done that in a very long time because I just straight up ignored him.
Every once in a while I get dragged to the KH and I'm immediately hit with "Oh I've missed you. How you been? I've been thinking about you"
All I can think is that if they really did miss me, they could easily call or something. They all have my number. I know personally if I am thinking of a friend or relative it takes about two seconds to reach out and say hi. If these people really were friends and a worldwide brotherhood they'd do the same.
