Spray and Friendship

During my second year of elementary school, I went to play at Igami's house almost every day. I had thought it was because Igami didn't want to go out much, but by the time we were in third grade, it seemed like Igami was walking around here and there, so perhaps it was just my own assumption.

The house next to Igami's was vacant.
When I climbed the wall and peeked over, I saw a surprisingly large garden. The garden was overgrown with weeds, and beyond the weeds was a concrete staircase. Climbing it led to a laundry drying platform.
On the side of the laundry platform, there was a sturdy-looking iron door. The door had been painted blue, but it was rusted in places.
"I wonder if a zombie will come out if we open that?"
"Maybe it's a Kuchisake-onna."
"What about Bunta Sugawara?"
"Maybe it's Bunta."
Peering over the wall, we gradually became excited.
"Shall we explore?"
"Let's do that."
We jumped down from the wall into the garden and pushed through the grass to approach the laundry platform.
When I grabbed the doorknob, to my surprise, it turned smoothly. It wasn't locked.
"It opens."
"Let's go in."
Even after opening the door, nothing came out. There were no zombies or Kuchisake-onna. Bunta Sugawara wasn't there either. I knew that from the start, but I felt a bit let down. I wouldn't want a zombie or a Kuchisake-onna, but I wouldn't have minded Bunta. Even so, that was just my own convenience, and it was a matter Bunta himself knew nothing about.
Underneath the laundry platform was a garage. I knew that from looking at it from the outside. The garage shutter was closed and it was pitch black inside, but since light shone in from the door, I could see what it was like inside.
When we entered, there was a tattered shelf in the back, and a spray can was sitting on it.
"What's this?"
"Let's take it outside and see."
When we brought it out, there was a picture of a flower on the can, but the instructions were all in English, so I didn't know what it was.
When I tried pressing the button, expecting a mist of chemicals to spray out, white foam dripped out with a sizzling sound.
"Whoa!"
I was quite startled and threw the can away. The foam had almost gotten on my hand.
Seeing that, Igami doubled over in laughter. He had a way of enjoying things without taking any risks. Watching Igami laugh endlessly, I thought to myself, 'You jerk.'
