Rant !!!!!!

What ever happen to the day when a person told you something and they done it? I've been trying to sell some parts on craigslist for a while and I will get calls about them, Some Joe wanting to come and check them out .Tells me they will be here at a certain time and then I wait but they never show, No call telling me they can't make it or nothing. With almost every one these days having a cell phone it just doesn't make any since to me. I'm wasting my time waiting on them, No body gives  respect any more. I know I'm ranting but things sure have changed since I was a kid and not for the good.
