I can only speak for my own MLCer, but he bought me Slurpees. And Jersey Mike's sub sandwiches. And rolled tacos. In fact, once BD happened, many things I used to ask for happened. After a 3 week sprint of high replay where he ended up barfing his brains out after drinking too much, he suddenly started calling when he was on his way home (I had a live in for 18 months). Telling me when he was going out. Coming home when he said he was coming home. And Slurpees, tons of them.
I still have no idea what it was about. That was during my observing him like a bug in a terrarium time. It's all very strange.
