Fill it

You fill my car with gasoline
I have some left, but my tank is nearly empty
Lately I've used too much and recived too less
Please fill the tank before my car stops

Now replace the words
"gasoline" with "your love" ,
"tank" with "heart"
and
"car" with "love"

It will look something like..

You fill my love with your love
I have some left, but my heart is nearly empty
Lately I've used too much and recived too less
Please fill my heart before my love stops
