Depend can be traced back to de + pendere, which literally can be translated to “to hang down from”. To be dependent on someone then means that it is someone you would trust to hang down from.

A person you can depend on should be treasured just like a valuable pendant hanging from your neck. Remember though to let these amazing people swing freely and let them be pendulums, swinging back and forth. Sometimes supporting you and sometime pushing you forward when you don’t want to go on. Sometime standing by your side and at other times swinging away discovering new things and new experiences they can bring back to you.

They will always be there though when you are hanging down from an edge to help you back up.
