Do people really forget you after they're successful?

Have you ever climbed up a staircase? Ofcourse everyone has. That was a stupid question, isn't it? But have you wondered that simple journey of yours could give you an important life lesson?
When you climb up a staircase, you put your feet on them carefully so that you don't fall off. If you are week, you hold the railing cautiously so that it makes you firm. You check weather they are wet or not so that you won't slip. You check weather they're broken or not so that they take you to your destination without any disturbance in the way.
Ultimately you reach your destination with the help of the stairs. But after that day do you ever remember which colour was the floor? Do you ever think whether it is wet or dry? Broken or stable?
No right? Same things happen in case of humans too. However, not all humans can relate to this. This holds true only for materialistic people.
People care for you so that you care back. They talk to you so that you talk back. They hold your hands and walk together so that you will hold them if they fall. Today's era revolves arround the give and take phenomenon. And ultimately when the give and take is finished, the relation ends.
