The day my best friend's grandma passed away, we stopped in a Petco near her apartment and an animal shelter had multiple kitties on display for adoption. My friend and I saw a little black ball of fur and impulsively decided to bring him home.
I should also mention, I was never was a cat person -- I grew up with dogs, and thought cats were mean and vicious.
We had our home visit from the shelter woman and she told us to invest in screens for my friend's rental apartment but she didn't say anything else. We had some food, litter and toys, and I figured it would be simple -- then a few hours later I lost him.
I searched high and low in the apartment, in the hallway and in the elevator, I even went to the doorman to ask if he'd seen a kitten. He looked at me like I had six heads. It had only been 6 hours and I already managed to be irresponsible. Finally I heard some rustling and found him buried under the bed asleep in a box.
