There are a great many things out there that I think I can do without quite easily: make-up, fancy clothes, high heels, T.V./video player, microwave, handphone, aircon, icecream, hot water and yes, even chocolate.
I was having that conversation with a friend from India, and then we got on to what we didn't have when we were growing up, but had now and just couldn't do without...
I said: The internet, because it is my way of keeping in contact with my scattered family - on a daily basis if we want - as well as a valuable tool for my work as a writer and a way of maintaining friendships.
My Indian friend said she had once posed that same question to an elderly Indian lady, to which the woman replied without hesitation: 'Running water.' As a child and young adult, much of her day had been spent getting water from the river.
I'm still grateful for the internet, but ... yeah. There are other things which might be a tad more basic. Which many folk still don't have.
