Dear my Student [이름],

A good day also to you! ^.^

We are also experiencing a hot weather nowadays.

However, it is not too hot.

Our temperature these week ranges from 15 degrees Celsius to 24 degrees Celsius.

Not all parts of the Philippines are experiencing an extremely hot weather.

Anyhow, I am glad that you have your own fan.

I envy you somehow.

I would like to have a pocket fan.

I am a person who sweats a lot when under the sun, so I really need something to cool me down.

Anyway, I hope that the air conditioning system in your company will be okay to be used soon.

You are right! ^^

Let\'s overcome the heat wisely! ^^,

That\'s all for now! ^^,

Happy reading! ^^,

See you tomorrow! ^^.

Good night! ^.^
