I just had this very conversation with my husband yesterday while we were out skiing. I was annoyed that there were a lot of boot prints in the tracks (in a public park—not dedicated trails). But then I remembered that before I took up x country skiing, we were snowshoeing in the same park, and my husband had to point out that I was ruining the ski tracks, because I was oblivious. I suspect this is the case a lot of the time—people just aren’t aware. If they are, and do it anyway, it’s not cool. But I realized I had to give people some slack because that was me just a few years ago.
