I could have just walked in the shop and bought the items
Which means: finding the car keys, driving into town - finding somewhere to park - waiting in line for a catalogue - searching through the catalogue to find the item - writing the item on a piece of paper - going to the counter to wait again for a sales person - searching your pockets for the screwfix card - searching again for your credit card - trying to remember your card pin number for this particular card - waiting for the payment to be authorised - then find the banks computers are down - searching your pockets again for enough cash to pay for the item - going home without the item because you don't do cash anymore in this modern era.
Quicker to shop on line and use a password program such as Last Pass to remember all the passwords for you, just need the one password (to rule them all) make it a sentence (containing symbols) that you can remember i.e. 4got Your Pa$$word again?
