[Pic cr ❤it.me]
Just now, I found today's also PI (π) Day because the beginning of Pi is 3.14 and today's 14th March. If you research π in baidu, see what will happen. All I can tell you is something interesting happened. After introducing this new festival (because I think you're not familiar with this day), I'm thinking about looking for the reason that causes me pleased.
The most possible reason I think is Mallory and I have done all of the homework problems about circle and ellipse before tomorrow's Algebra quiz. I just need to review them and we don't need to think it too hard because we have already finished them. But we almost spent every study hall after lunch on these problems. During the thinking time, we met lots of difficulties that we couldn't understand. We even made mistakes lots of times, but at last we found the mistakes and fixed them immediately. Then we got the final answers, that means, we succeeded.
Success will make me really happy?! Well, now I know the answer why I feel so happy……
