The English school is around $30 a month for one student, a little more expensive as you get into higher grades. The school is nearby, but I guess everything is here in Pramaoy. I would estimate it's not even 2km, but it's still convenient not to make that back and forth trip 4 times a day. Only $10 per month to have both girls be taken from and to that school via Prius taxi.

I calculated I can easily earn that $10 on HIVE with the extra freetime I have from not making that short drive many times a day.
