I've never swam for exercise in lanes before, but I always assumed you'd only have one person in a lane at a time. How does it work to have two in one lane? If I'm swimming and someone wants to share my lane, do I swim out, wait for them to get to my side, then swim back when they reach my side? (And if I'm the slower person, I assume I start swimming behind them as soon as they launch off from the edge?)
It'd also be a shock to me to see a second person just simply joining me in my lane. Is there a protocol for joining a lane other than, I guess, flagging me down and asking? Do people normally know how to accept having a second person in their lane?
Funny thing to be asking so many questions about...
