It’s still very common to hear older people say, I don’t do mobile phones, I don’t do computers. It’s as if it’s a badge of honour. They may as well say, I don’t do cash machines; I don’t do televisions; I don’t do washing machines. All these things require a few buttons or keys to be pressed so no different to a computer or phone once you get used to how they work.
I would categorise reluctance to drive differently as some people do seem to have a genuine fear of getting behind the wheel in case they cause an accident. A reluctant, timid driver is a danger on the roads.
If your cousin is a retired teacher and worked in the school system until state pension age I wonder how she avoided working with children on classroom computers or with an interactive white board.
Considering home computers and mobiles phones have been around for decades; the smart phone (as we now know it) for almost 20 years; it suggests technophobia/technofear. I sometimes suspect it is a reluctance to admit they may need a bit of help getting started with something they have never used. It could also be a fear of being scammed if they go digital. I’m inclined to think that programmes such as Scam Interceptors are helpful but also create unnecessary anxiety.
And why write to ask? Does she not have access to a public library where, even if she doesn’t have a home computer, smart phone or broadband, she could get the data she’s asking for there?
Your post begs the question why does she want the postcode? Presumably she is going to ask someone else to locate the restaurant for her using a digital mapping app.
Every time something comes up about digital service (e.g. the possibility of ID cards), we hear a lot about digital exclusion but I do wonder to what extent many of those “excluded” are deliberately entrenched refusniks. It would be interesting to discover the true reason(s) for their reluctance.
Perhaps, when you meet your cousin, you can have a chat with her about this.
