Concerning My Last Blog

Just one more thing everyone. I did something new in my last blog. I combined two adjectives in one sentence, as such: むずかしくてただしかったですよ！ It was difficult, but fun! In order to do so, I converted: むずかしい into むずかしくて In other words, I took off the -い at the end and replaced it with -くて. I think this rule only works for the -い adjectives, but I'm not sure. Any help would be appreciated! ありがとうございます！ -メイサン
