You see someone and they say hi and you say hi and then you go eat and laugh and then you die.

I saw my friend at the pizza place. We said hi. We ate. Now I'm dead.

My dad saw my uncle at the bar. They said hi. They drank. Now my dad is dead.

I saw my enemy at the library. We said hi. We read. Now I'm dead.
