I thought holding hands is what 9 out of 10 elderly couples do in this country?? At least I remember it struck me when I moved here 14 years ago, I remember even commenting to my mum, that old couples always hold hands in UK (not culturally common in my country of origin and usually not that many elderly couples about - either divorced or men died first. Might be changing now)
Anyway, apart from the OAPs - and I'm going to be in town today and will properly look, I'm sure all elderly couples I'll see will hold hands. My PILs always do, but MIL can barely survive on her own while FIL is in the toilet, so that's not surprising 😀
Anyway, I don't normally even register whether people of other age groups hold hands (I hold DH's hand sometimes though more likely to have arms linked and also, giving it thought, suppose I'd agree it's less PDA). But last Friday I did notice a couple of leaving along with me our DCs sports day and holding hands and it bothered me a little, I couldn't understand why at first.
Then I knew, they were walking along the road holding hands and woman gazing up at her DH, while their two young primary school kids were walking by themselves(not holding hands) behind, that was kind of weird. Maybe they just know their kids very well and know they would definitely safely tag along?
The other one is where I do notice and find it annoying is where couples hold hands and take up the whole pavement so I have to let go of my DC's hand and stand in front of one another to let the couple who won't unlink past
though it's pretty rare. And couples holding hands walking round the supermarket, also makes for tricky shopping even with a basket, I think the basket carrier would rather not but isn't given a choice usually :).
Everyone who said OP would hate them: it's obviously light hearted and she's not losing any sleep over it, she also said she might do it occasionally herself, she just doesn't understand holding hands at all times, which I can totally sympathise with, YANBU :)
