As a borkuist fluent in borkinese, I can translate this:
Guy: What's wrong?
Gabe: I can't...
Guy: Huh?
Gabe: Hah...
Guy: What's up?
Gabe: Do you know what it means to be mortal, father?.. It means I will die. I'm afraid to die. It... it's not that I'm afraid of what awaits me. It's that I will leave you alone. That I won't know what becomes of you. That I can't comfort you in times of sadness. That I can't be with you in times of joy. There is a selfishness, but most of all I worry about you. We give each other meaning. What will become of you without me? That is what I'm afraid of. That you will be alone when I'm gone. So now, while the time is ripe, while we are still together... can we go for walkies?
