It's nice to hear you have a nice day.
I'm curious what company you are working for. It's a public organization or a private company?
And thank you for your Thai language lesson
That really helpful. I finally know how to say hello in Thai language.
And ofcourse I would give you the English lesson
"Today I was happy"
We won't say that. Because "I was happy" means you dead and feel happy when you alive. "Today I am happy" that's the correct sentence.
Have a good night my dear. And hope you will have another wonderful day tomorrow.
