We can not cannot go back in time

The Last sunday I watched the movie: The curious case of Benjamin Button, and there was something that an old woman said it called that caught my attention and broke my heart.
``´The loved persons people have to die to we for us to realize the huge space and importance they have in our life´´. I started to remember all the times that my aunt came to visit me and I didn´t want to wake (get) up to say good bye goodbye with a hug. Now she is not in this world and I can not cannot/can't go back in time and give her a hug.
So go and say: I love you to someone you love because you never know when it's/ it is the last good bye.
