You say no as that’s just not you anymore. Dave understands and smokes it by himself.
You two continue to have a good conversation until you get tired and want to just leave the park. Maybe you’ll go home, maybe you’ll go somewhere else.
As you are walking away you think about how you said no. You have some regret and think about turning around.
After a moment this seems foolish and you continue walking.
Preoccupied by the thought of turning around you don’t look at the walking sign and walk straight into traffic.
A bus hits you and kills you instantly. Is this really how you want to die?
