do dogs understand concepts like chairs?

Today I got really ambitious and decided to take Pebble outside to make her go to the bathroom. After Pebble throughly sniffed every inch surronding our crockpot which was simmering our future dinner, she wobbled over to the grass to further smell around. While I was waiting, I struggled to slide myself into one of those wooden, beach, boardwalky chairs that we have on our porch.


it was like this



As I scratched my legs, bonked my head, grasped for life in the chair and Pebble stared obliviously at me, a thought hit. Does Pebble understand that I am slowly dying in a chair? Does she understnad that this contraption is for sitting? I finally pulled myself out of the chair and continued to ponder whether or not Pebble knew I was sitting in a chair. Then another thought came up, which had nothing to do with what I was thinking about before. What if people think I'm weird? To be honest, this is not the first time I have thought this, I know that I am definitely a little strange, but I just have a feeling that this year everyone is always acting like I am being completely strange all the time. I got a new seat in spanish this semester and I always feel like everyone is looking at me. See, our room is split up into two halfs so we are facing one another. I don't really feel like explaining it so you throughly understand so I just made you an illustration:

it's really small, but I honestly can't get it to work

and yes all of our desks are semi-circular/almost square. It promotes creativity. But anyways, I just always have this feeling that everyone on the other side is totally looking at me. And it's freaking me out. I'm really concerned. Bth then again, everyone in my Spanish class is completely insane, so I guess it doesn't really matter.

I'm still not sure about the whole chair thing.

Cheers,

Cayla
