A friend of mine told me that installing a roof rack on his car was the moment when it really struck him that he is a dad.
“More so than the birth of your daughter?”
“Yes.”
I cannot fully vouch for his claim as I paid extra at Halfords for a teenage lad who was, I think, stoned, to install ours while I sat in Starbucks, sipping a latte, but I can see his point; a roof rack confirms your youth is over.
