I agree with Kano's observations. If you're that kind of person being the slow one really sucks. I can get really childish and upset and cranky if I feel that I'm keeping someone back, while still trying my hardest, especially if that person is just whooshing back and forth filling time apparently with no effort.
When I started cross-country skiing some years ago, after several trips apoplectic with distress, I made a deal with my dh - he stays BEHIND, and he does NOT overlap my skis. That let me set my own pace, stop when I wanted to, and not feel pushed - and let me hide my face when I was really struggling. Stupid, I know, but that's just what it was like. Now we're much more closely matched and I've mellowed out anyway so we don't do that anymore, but I try to observe the same thing with our son and give him space when he needs it to feel on top of things.
It can be tough if your mental image of yourself doesn't match reality, and realizing there's a mismatch doesn't necessarily help the feeling of substandardness.
Winter riding is much less about badassery and much more about bundle-uppery. - malkin
