Ahhh... I just thought that archers learned how much offset there would be and aimed from that.

When I tried a bow (a longbow as it happened), I continually sent the arrows far to one side (the side it was nooked on of course). I simply couldn't understand that as I did exactly as the instructor told me... I ended up sending four arrows deep into a wood, never to be found again.

After that I have not touched a bow as I feel cursed.
