Speed dialling means I don’t know anyone’s numbers anymore.
If I break my mobile while fleeing the zombie hoards, but manage to get to a phone box, I’ll only be able to phone the following people for help:
1) my mum (same mobile number since 1993) (she’s not always in the country though)
2) My school-friend Michelle’s parents (I dialed their landline a lot in my teenage years, number is seared into my brain)
3) The Saturday Swap Shop number (defunct since the 80s)
I’m screwed. Especially if Michelle’s parents are out.
