My Oh is obsessed with construction what I call 'tonka toys' but the big proper versions - Big diggers, JCBs, Tractors, Things with names I don't know and never want to..... but I just don't get it.
He works in construction but is in the management side of things so has never driven any of them. For his birthday I paid for him to have a special one-on-one lesson and play with a big digger at Diggerland. I sat and watched him for a bit but it just looked so boring. He dug a hole. A big hole. He filled it in again. I thought I had bought him the worst birthday present ever but when he came back, he was absolutely buzzing. He thought it was the best thing ever. He has told everyone he knows the specs of this digger like it was some kind of supercar. It's just completely lost on me. But then he doesn't understand my obsession with shoes.
So does your OH have an obsession you don't understand or vice versa?
