At around 10 PM last night, I spotted a massive cockroach on my wall. I grabbed my insecticide, aimed at it, and pressed the nozzle and nothing came out.
Infuriated with myself because I had completely forgotten to buy a new can after finishing the last one.
So there I was, standing in my room at 10 PM with a cockroach on the wall, all the stores already closed, and no way to deal with it.
In the end, I had to knock on my neighbor's door and ask if they had a can of insecticide I could borrow. Thankfully, they were really nice about it and gave me one.
Needless to say, buying a replacement can is now at the top of my to-do list.
