The gym logic is very weird.
Expensive phones and airpods are left everywhere & no one touches them.
But leave your 7.5 kg dumbbells unattended for a second & they are gone.
One of the healthiest things I’ve learnt over the years is to allow people reintroduce themselves to you, even those closest to you. Familiarity shouldn’t become a cage. People change. Love them for who they are now, not just who they were then.
