To be annoyed that I get glared at for having a blue badge

I don't think you're being unreasonable to be annoyed at being judged by older people who think you can't be disabled because of your age, but I do think you're unreasonable to get upset about it. They're just showing their ignorance. You don't have to show anyone, apart from the appropriate authorities, the photo on your badge, which is why you place it with the photo down on your dashboard. Just tell them that you have a blue badge and are entitled to park where you do, other than that, it's none of their business. I must admit, as a younger person myself, when challenged once by an elderly couple as I reversed into a disabled bay, I quite enjoyed waving my blue badge at them, and continuing to pull into the space. They obviously felt they were more entitled to the space than I was, but once they saw the badge, they had no choice other than to drive off and find another space, as they didn't have the advantage over me, that thought they had when they pulled up beside me.

YABU for letting them annoy you. You have a badge that you are fully entitled to and are disadvantaged compared to many who are judging you, so don’t even bother giving them space in your head.

I hear you.

My ds has a blue badge as he has a condition - like yours - that flares up.

He can be sitting to standing or just walking along and his leg spasms and he can't get it to go down to the floor. He's then a 1 legged person!

I think see a fit young lad (although he wears a splint but that can't be seen under trousers) and wonder why we have it.

They don't question it when his hopping along on crutches or in his wheelchair!

Honestly - easier said than done - but use your energy to worry about you and your health.

And next time you're asked for proof ask for their council badge to prove they are parking enforcement as state you'd hate to accidentally disclose personal info to a random busy body on the street

How dare you insinuate that older people are uneducated and all hold these kind of views.

People like the ones the OP mentioned, will have been dickheads when they were younger.

You don't just become old and suddenly become a bigot.

Young knob head = old knob head in case you need it explaining to you.

You sound uneducated to be honest. Assuming all older people are the same.

It's rough. I've had a few 'looks' and most duck head when i get my cane out the back seat... the one's that persist i generally just glare at in an 'excuse me?' kind of tone.

Only once has anyone had the balls to ask me if it's mine and i just firmly told them to mind their own business.

Since yous are quite young may I suggest you roll back to even younger next time? Do that teen thing where they rummage in a pocket then pull out a hand with a middle finger up? Then smile and walk away...
Def make you feel better imo.

Glare back none of their business

Flip 'em off.

Unless it's a traffic warden or similar just tell them firmly "it's none of your business" and ignore ignore ignore 🙂
