Margaret, lots of adults don't drink water! I grew up in the 70s and 80s in Glasgow and view water (bottled anyway) as a bit new fangled and definitely something young uns drink : I align it with the also new fangled gym culture. My gran didn't drink water, my (really rather posh) dad doesn't, my (very posh) step mother doesn't. I don't like seeing people glug out of bottles.
I don't go out for work meals - but if I did I'd have lemonade (or wine). Someone else might ask for a jug of water at the table,, sometimes. I'd top up my wine with it .
During the day I drink tea.
DH drinks tap water every so often and has a drink of water before bed but , if offered a drink, he would have tea.
We are not weird : this is perfectly normal behaviour! Squash is not really an adult drink.
You move in quite rarefied circles. Every adult in the world does not go for work lunches or go to the gym or for runs! If I did do exercise , I would have water...
I agree with a PP about the bottled water industry making a mint out of us. I am one of those stupid pole that if I drank water it would probably be bought for a shop!
Our fridge has a water dispenser thing : the kids love that in the summer and I have been known to have a sip. Generally my aversion to water is about not wanting to pile gallons of any fluid into myself.
I do like eating ice cubes though! But I admit that bit is odd.
