As to bad(which I am certain i like this part of the meme,but here goes) she seems always a bit random which could be problematic at times. I also can tell there are some times she seems like maybe she doesn't feel as happy go lucky as she pretends but puts on the show on the image anyway cause it seems like it is expected. Being your friend means we will listen and understand when you have problems too.
Overall those are pretty minor flaws. You are as I said, one of my favorite people and i am glad to know you.
