Narrator: “Everywhere I travel, tiny life. Single-serving sugar, single-serving cream, single pat of butter. The microwave Cordon Bleu hobby kit. Shampoo-conditioner combos, sample-packaged mouthwash, tiny bars of soap. The people I meet on each flight? They're single-serving friends. Between takeoff and landing, that’s all we get.”
Narrator: “Man. This girl read one of my posts on Reddit and messaged me last week and told me I was interesting and wanted to chat with me.

Tyler: Well, what happened?

Narrator: She ghosted me after the third day. I guess I was just a single serving friend.

It is ideal if both of you in the relationship choose a celebrity free pass so that the playing field is even.
