If men owned handbags it would be like this:
1) One bag would suffice for months, probably decades.
2) The contents of the bag would be as follows: Wallet, car keys, prophylactic (use by date 09/07/1998), phone, photograph of pet/car and the Topeak McGuyver multitool.
3) Once items were in the bag, they'd stay in the bad until such time as they were needed.
I've lost count of the amount of times my g/f has mounted a frenzied search for a mobile phone or set of keys that have turned up in a forgotten bag compartment.
