Think of your current relationship with people how is it. Your new acquaintances your old contacts your friends your family they are all different than what they used to be. Your equation with people varies over time , experiences and interactions.
You cant do one big good turn and be remembered forever, you need to be constant, continuous and current on things that you do.
Terms like you used to be this or you used to be that, or she was very nice intitially or she was very helpful at first.
You want to be liked, admired , spoken to or relied upon , you need to be at it.
You cant slap somebody without reason and expect them justify that you are liked for some past huge favour
Go be your best always
