To answer your question. I’m right handed and when I kick off a ball I use my right foot so I’m an all right chap.
But somehow it wouldn’t sound right if a drill-sergeant bawled out, “Right, Left, Right, Left” although (during the American Civil War,) I’m told, they bawled out, "Hay foot, straw foot.
Does any Army in the world, me idly wonders, step off on the right (straw) foot?
But, LolaBaby, the thought was triggered while putting on pants so may I ask you, "Are you left or right handed and do you ALWAYS insert the right leg first?
Now see where idle thoughts may lead!
Hang loose LolaBaby.
