I can't fucking stand the endless abuse of car horns.
I've noticed that there is very little human interaction when I am walking around. People are all over the place in this very busy city that I live in but every now and then I will say "hi" to a stranger when I am walking and they couldn't even hear me because everyone, especially younger people, can't possibly do so much as walk without having their phone in their ears. It is seen as creepy to speak to a stranger now.
Just like @bozz was saying above though, the use of some tech is warranted and that is fine but not to the point where you don't know how to do anything because your machine will do it for you and this is especially true with simple calculations. I am regularly in shops where all of the prices are rounded off to the nearest 5 or 10 yet these young people at the counters always revert to a calculator even if the two items I'm buying are both 20k each. One time I went into a store and was buying just one thing and the person behind the counter had become such an automaton that she entered the price in the calculator and then pressed "=" .... I guess she just needed to be sure.
That's horrible. I was a math minor in college for a while and I actually found the deeper I dove into calculus and stuff like that the more I forgot how to do some of the simpler stuff. Pretty sad huh? That being said, working in Radio Shack made me pretty adept at making change.
