Natural high

Hi guys!! How you doing?

Me? I'm sooooooo exhausted!  

I slept for only three hours today. 

Why?

Last weekend I didn't study so much,

and this week I was tackling  

difficult homework problems for special relativity.

So I had to write a report for the lab class until 5 in the morning.

I yawned thousands times today!!

I'm going to bed. Good night!

睡眠３時間はさすがにキツいなあ。

先週末はまったり過ごしたのと、

特殊相対論の宿題にハマったのが重なって、

実験レポートを朝5時まで書くハメに。

目がしぱしぱする。。。

もう寝ます。おやすみなさい！
