I am a fan of Yoojung Lee. Her dance moves are sharp and beautiful.
And I like her coolness.
I’m sharing her dance moves with you.
If you’ve been following my Twitter timeline, you’ll have an idea of what I’m talking about.
It’s the type of person I like quite a bit.
These days, I’ve been thinking that the women I like are very similar to each other.
There are about three patterns, though.

She is as unattainable as the stars, so I’m a fan of hers.

I just want to watch her.

April Fools' Day :)

Today is April Fool’s Day, isn’t it? Let’s all be careful not to be deceived by lies and hoaxes. Incidentally, I think Google will also release their annual lie app.

The video is not particularly meaningful.It’s just that it was the name of a channel on YOUTUBE that has the same name as where I live.

### mysql case = if文みたいなもの
```sql
select namae,tensu
case when (tensu >= 75 and tensu <= 80)  then '可'
when (tensu >= 25 and tensu < 75)  then '否' else '???' end as kahi

プログラム言語って使用しなければ抜け落ちるです。
自分の場合、たぶん長期的な記憶に障害があって抜け落ちるですw🙄。
メモしたことすら忘れてしまう…これは痛い老害？。

でも、好きな事は大体覚えていますね、概念的な事を覚えていたら大丈夫です😌。
