Taking care of a person can be more exhausting than hard physical manual labor.

If the person is in a negative frame of mind, being hateful, cynical, skeptical, 

confused, angry, stuck in a loop of doomsday thoughts and words and actions

this is a drain that can suck your positive energy right out of the pipe of hope

and down to the highway of hell (misery).

Enjoying time with pleasant, happy, fun loving people and animals can be

exhilarating, make one want to spend more time with them and have

something good to look forward to.  A reason to live. 

Recharge yourself with rest. Remember your youth. Relive your

innocence. Share the sweet spirit you were born with.

Enjoy the sweetness of nature.
