There are many reasons for lateness; and if they do care about you or the situation they will get there. As people in this day and age, I think we are too quick to assume if lateness is an issue they just don’t care. You don’t know what might be going on in somebody else’s life. If you jump to conclusions that they just don’t care, sadly for 1 out of 5 people nowadays that may be the case. However the minorities once again strike, because of what we see and hear on the news. There are still good people out there.
You don’t know what’s going on in somebody else’s life or mind that could cause them to slip up or not be somewhere on time. If you contact a person via email it may be that they’ve not picked it up yet or they have but are just a little bit busy to get back to you currently. But they will get in contact in their own time. And if they don’t, it’s their loss. That’s how I look at it anyway!
Don’t jump to conclusions so soon! I know it’s hard in a world of instant messaging and texts being able to be sent from anywhere. But you’ve got to have an open mind. They could be having the worst day of their life, someone close to them may have died, honestly anything can happen just out of the blue in this life, so please don’t think they don’t care outright. In time, you’ll see that patience is a great virtue and maybe it would be worth it to give someone another chance.
