I may be the worst bow hunter ever! Or the dumbest!

My brother has been giving me his hand me down bows years. 2 years ago he got a sweet new Matthews. So then I had 3 bows to choose from. So one morning, I get my camo on and grab the best bow avialable. Later that morning, I missed a nice 8 pointer about 20 yards away. I figured I would go back and practice on my shooting. Well, everyone is back at camp and we start shooting the bows. I am missing the hay stack badly. I couldn't hit a barn if I tried. So my brother grabs the bow aims, fires, and bullseye. I couldn't figure it out. So the next shot I have, I hit the target. Everyone starts laughing and I said, "did you see that, I hit the target." They all are rolling around, laughing their ass off, screaming, "It bounced off the ground" I then decided to to try another one of the bows. Same result. Again, my brother grabs the bow aims, fires, and bullseye. I said whatever, I'll try my luck in the woods. I am not going to see any deer her with all this laughing going on. Well I didn't see another deer and that was it for bow season that year. Last year we went up north again and it was the same story. I couldn't hit a barn. About 20 minutes into it, I was fed up. I asked my brother again to shot the bow to make sure it was on. Of course he hot the bullseye again. THEN finally my dad's buddy say's to my brother "I didn't know you were a lefty!" I could not believe it, I was shooting a lefty bow, righty. No wonder why I couldn't hit a thing and my brother was hitting bullseyes. Just goes to show, I am either the worst or the dumbest.
