Yoooo, if you gave me brainliest that would be pog, bedause as it turns out only a small percentage of the people who I answer actually give me brainliest. I need one more brainliest for the next rank, so if you could give me that, it would be much appreciated. It's free, and you could always change your mind later. Also while you're down there consider leaving a thanks on the answer to boost it in the brainly algorithm.
