So I live in a small town in Japan and I teach English at several different elementary schools. Today I was at the 100 yen shop (dollar store) picking up a few things and I saw they had individual adult diapers. I thought, what the heck I'll give it a try and I grabbed it without thinking too much about it and headed for the register. There I met three of my students. They all said "Wow it's Ben sensei!" and I quickly turned the other direction. They thought it was strange and I heard them say "Why did he run away?". I managed to put the diaper back without being seen and paid for my stuff.
On the way out I ran into two other students who instantly asked what I bought and tried to look inside my bag.
I can't even imagine what would have happened if they saw the diaper in my hand. If an adult co-worker saw me they might think that I have some medical condition or maybe I was buying it for someone else, and wouldn't give it too much thought. But if my students saw it, everyone in the school would know. Every single student would giggle about it every single time they would see me. I wouldn't be able to teach a lesson because that would always be the big elephant in the room.
The important thing is I didn't get seen with a diaper in my hand, but oh man it was really close.
