Nonsense, it’s simply in a world full of needy influencers & the like, some men (and probably women) don’t need or seek attention 24/7 we have lifelong friends but don’t live in each others pockets. We can go months without speaking to some mates & then pick up where we left off.
Middle-aged men are crap at maintaining friendships, it's true, but the reality is most of us have got pretty close to fuck all of any substance to say to each other. We just want some peace and quiet.
