Texting is often nothing else but a bunch of abbreviations. The question is, abbreviations in which language?
Maaf, aku terlambat 1 hr – Sorry, I am/I’ll be one hr late
Oke, aku akan tunggu kamu di mal ya – Ok, I’ll wait you in mall
Sepanjang malam? – All (through) the night?
Oh.. Kamu terlambat 1 hari bukan 1 hour – Oh, you’ll be late 1 day not one hour
Jam – hour
PS Besides wooden calendars there is rather interesting art in Indonesia as well.
