Moving cities doesn’t erase your old friends. It just tests which ones were built for distance.

Distance does not break anything. It just removes the scaffolding that was holding the friendship up without either of you noticing: the same corridor, the same bus, the same Tuesday. Take that away and what is left is whoever is willing to do it on purpose.

Be the one who sends the message first, several times in a row, without counting. Make one call a fortnight rather than waiting for a reason. The ones who come back to you with effort of their own are the ones to keep investing in.
