What are the things you do that most people take for granted?
Arriving on time.
This has to be one of the most annoying things I have seen people taking for granted.
A friend asks me to hangout for coffee. We decide that we will meet at my office and go together around 3pm outside the physics building.
I reach there by 2:55pm and the other person arrives a full 20 minutes late.
A friend asks for a ride to the restaurant. The time is decided and I reach his place 5 minutes early to pick him up.
I wait outside his apartment for 15 minutes. Turns out he started getting ready when I came to his place.
Moral of the story: I know time is relative but please be punctual and understand the value of someone else's time.
