One day, my colleague was going to the store for a break and I asked him to buy me a cigarette. He has never smoked, and he doesn’t even know what these packs look like. He asked me to drop him a photo of the cigarettes I needed, and I sent him a random picture of a Google package with a picture of periodontitis. Almost half an hour has passed, and colleagues are not there, although the nearest store is in a neighboring building from our office.

After another 10 minutes, he finally comes back and says to me, “Listen, there was no periodontitis anywhere! This is a painful death. Will it go?”

At first I thought he was joking, and we both laughed. Later it turned out that he was serious.
