I cannot help it but I am always looking for fellow Nappy wearers and find a fair few, on the other hand I live in a Nappy rich environment as most of us in this village are fairly senior and on bin day you would be amazed at how many cardboard boxes from well known brands are left out for recycling ( myself included) the most common ones are iD slips as they are NHS supplied but Tena are common as well as Abena and Lille.
Bin day is always interesting as someone always has a box or boxes out for recycling.
I break my boxes up into bag size chunks then put them out in the bag, that way only the person emptying the bag would potentially see the Nappy boxes.
Spotting Nappy wearing people is simple here as you only have to remember who's house the boxes were outside and look at the people there and observe the square Nappy butt or distinct Nappy outline, there have been many spottings out on the beach as people tend to let their guard down and few have been very obvious possibly wanting to be seen, but many are so discreet you really could not tell one way or the other and I would like to think that is the category I fall into.
Supermarket shopping seems to reveal a fair few as well especially when people bend over to reach something in the freezer, many a defining waist band gets revealed there
There have been a few people I have seen with the "half moons" developing nicely on the rear of their trousers probably myself on very rare occassions too !
then of course the one or two that set us all back by being really silly, I was on a train once and right next to the railway line in a field was a middle aged male showing off his Nappy
I could hear all the comments along the coach as we passed him as it was hard to miss the idiot.
I am always very aware of people wearing Nappies but unless they had a wardrobe malfunction of signifigance that could be easily rectified I would not dream of interfering in the matter as private is private and it is no business on mine even if I love the subject.
My Tuppence worth anyways
