I'm easily irritated, i wish i wasn't, but i am.
All these things bug me. people walking in front of me is very annoying. i rarely go to shopping centers these days, its too much hassle. Though when i am there i constantly find myself dodging everyone, who seem to be too important to do the same. i'm about 5ft 8, so not tall, but i'm 13 stone, so there is plenty of me to see. i'm too polite to walk into them though.
Kids running around in public places both irritate and amuse me (i have kids too, so i'm not judging parents here) They run at full speed, but only seem to look about 2 meters in front of them.
Shoppers with Trolleys.... get on with it!!!
i live and work, out in the coutryside, and its all the rage now, to go jogging along country roads, as if it wasn't bad enough. Run round the edge of the field, or find a road with a path dammit!
Since we are on the topic of cyclists, i don't encounter too many commuters, being in the country, but there are hordes of tour de france wannabes everywhere... at least the commuters are going somewhere. These guys will end up where they started! I dont see the appeal, your in the country! get off the road, get a mountain bike and go and enjoy it! It just seems odd to me.
my opinion on cyclists in towns/cities is that they are going far too fast. it takes them too long to stop at the speeds they are going. My Mother in law was hit by a cyclist while crossing the road. i dont know whose fault it was, but he hit her so hard, she had a brain injury, as she hasnt been the same since. She's always been a funny bit of kit, but now she's a right mess.
