You know what's great? Meeting those random people in stores that you become best friends with for the next 5-30+ minutes you will never meet again.
I had such an encounter at Barnes and Noble today. After talking for a pretty significant amount of time for such a store encounter, I had to laugh when these two guys had to leave. One looked at his phone and realized that they had to go and the other looked at me and was like "Ah sorry. We've gotta go. I'll see... you... laaaaaateeeeeerrrrrrr..............." and upon realizing the falsehood of the phrase in the midst of saying it, they hurried away rather awkwardly the word "later" still hanging in the air. I'm pretty sure it took him a full 3-5 seconds to finish the word as they exited the manga aisle and turned the corner.
Made me chuckle.
Fare Thee Well Manga Fans that I will never meet again. I hope you heed my manga and anime advise.
