huh well a different world now. I was born after, and we have cellphones/smart phones so we can know where people are at.
It frustrates me when older people don't know how to use them, and make excuses that they can't txt, or call someone or organise their own social life, or understand how to use voicemail, or know they are not supposed to answer calls while driving at the same time unless its hands free.
People are late a lot because of traffic, but they do apologise, well to me they do. Then they learn to leave a leeway of 5-10 minutes before moving on. Most do text and say they are on their way, or running late.
So maybe you are being too hard on people, and expect your life to run like clockwork. You sound like you get really angry when it doesn't, and that can scare people away. Time is money! Hurry up sort of attitude. God reminds us to be patient. All good things come to those who wait and even Jesus was late sometimes.
