Konnichiwa(Good afternoon), Film,
How are you feeling today?
By the way(BTW), I'm going to your city next month.
My schedule; Arriving BKK: 20-Oct(Mon), evening / Leaving BKK: 05-Nov(Wed), night
During my stay there, would you like to go traveling together with me (and your mother, of course) to wherever you want?
If you are free and available, that schedule will be a trip of three days and two nights; Fri-Sun or Sat-Mon, that is,
24-26/25-27-Oct or 31-02/01-03-Nov.
Discuss with your mother on this matter very soon. Then, in case of "Go", I would like you to make that plan and also arrange a suitable [Package(d) Tour, including round-trip transportation and accommodation, at least].
Awaiting your reply.
