Last night, a vendor went across my house and she asked me to buy some fruits
for her. Because it was late and she wanted to go home with everything sold out,
she sold at very cheap price. I bought dozens of mangoes and guavas (4.5kg) with
only 45000 VNĐ (about 2$). She said many times "thank you" but I think I should say "thank you" to her first.
