I just got yelled at out a car window for the very first time. Didn't catch a word of it. I'll assume it was encouragement.
To be fair, I WAS being somewhat unpredictable immediately prior. I was biking with my boyfriend for the first time, and he's not used to biking on the road. We were occupying the rightmost lane beside a lane of parked cars, when the parking area ended and a new rightmost lane opened up. I signaled to take it, but he didn't see me, with the result that we both scooted right but ended up sort of on the lane divider. Then the guy behind me honked, which SUPER helped me communicate with my partner (I had to shout), we merged right, and someone in the backseat shouted at us as they passed. It's hard to care without even knowing what he said, though.
Related: that was an EXTREMELY aggravating stretch of road to bike, with constant switches between bike lane present, parked car lane present, three lanes with rightmost marked to share with bikes, or - at one point - just two marked lanes, but the right one was double-wide. I'm enjoying my commute, but that ride was stressful. It's too bad the library is on the other side of it. I might honestly rather walk 4 miles round trip.
Final note: I just received my combo bike light and horn, so I am improving my ability to communicate! Kinda psyched.
