Flying into Bradley International (KBDL) last night, JetBlue was coming in to the same runway, so the controller advised that I'd have to do a little maneuvering because of the JB's descent rate/airspeed being significantly greater than my measly 172. No problem, not the first time. So he says, "You'll be number two behind the Airbus." I (mistakenly) replied, "Number 2 following the Airbus." He graciously corrected me, but I learned that behind just means sequencing, following means that if you have visual contact, you can proceed inbound behind them. In this case, he did NOT want me to follow visual contact for obvious reasons (namely wake turbulence). Nobody got bent out of shape, and we successfully executed the remainder of the approach and went on our merry way, but I learned an important lesson: wording matters! Wasn't sure whether to post this in here or Lessons Learned, but I was with an instructor, so here you go! Edit to add, this was on an IFR flight plan, and we were receiving vectors for an approach different than the one we initially planned with ATC due to additional separation issues on the intersecting runway.
