what would you want to remember to tell to you if you get dementia?

Know that when you leave,
Know that when you leave,
by blood and by me, you walk like a thief,
by blood and by me, I fall when you leave.

So tell me when you hear my heart stop.
You're the only one who knows.
Tell me when you hear my silence,
There's a possibility I wouldn't know.

So tell me when my sorrows over
You're the reason why I'm closed
Tell me when you hear me falling.
There's a possibility it wouldn't show
