Teachers at the Theppanya school in Udon Thani, northeastern Thailand, were all covered in red heart stickers after the school principle organised the fun activity for students to show off what they love. Inspired by Thai children’s craze for cute stickers, the contest was aimed to bond the relationship between primary students and teachers. Teacher who received the most stickers would become “Miss Valentine”. One beautiful teacher Chamaiporn Samoron, who was also had her body and face covered with stickers, said that she never received heart stickers as much as this before in her life but she was happy that the children were having fun.

I don't want to think about what I'll do when I have to remove them this evening.''
