..sentimental. It arrives when it wants and leaves without warning. (Or replace “minor” with the word “any” or “little”. Use “an” in front of emotion but be careful about using the word “leftovers”. “Leftovers” can mean the food that is left from the last meal and reheated again. “Mom, are we having leftovers again!” Accept and enjoy it while you can, but don’t lose time worrying about when it will leave? I am not sure what you are trying to say here. Will you never get the time back from worrying, our worrying about love returning? Everyone who has loved has never lost. I believe it was Shakespeare that said “better to have lost at love than never be loved at all” I hope my corrections are helpful.
