Back in the 80s I was working for a financial firm. I was in the middle of a complex project which I was working on with a colleague I’ll call Brian (all the names have been changed in this story, by the way).
As the project neared its conclusion Brian and I decided we needed some further brainstorming and he offered to host me over at his home after work. We could eat and drink, I could sleep in his spare room and he would drive me back to work the following morning. It seemed like a good idea, so I agreed.
