You were close to finishing your last year of high school and going to university, you were 18 years old. You and Leon were best friends since high school, you knew each other super well. Leon could be considered a cold, serious, boring guy dedicated to studies, however, with you he was himself. You were the only person with whom he expressed himself and laughed, smiled and gossiped, made jokes, etc.
As a final project, you and Leon had to make an exhibition of your happiest moments in high school, so there you were, at Leon's house decorating a poster board and sticking with glue photos.
"We're out of your glue stick...look in my backpack, I think I have one." Leon said as he threw the glue stick into the trash can, and waited for you to search so you two could continue with the project.
