Teacher's Day

My former teacher ever asked us to buy a fan for her on Teacher's Day she said just need pay RM3..but till now no1 pay also
I asked 1 of my classmates what they want to give to teacher..they said they don't know..I told them teacher asked us to buy a fan for her..
After he came back from school, he posted on group and ask all the people what to buy..and he commented  " Lily said she wants to buy fan for you" to teacher..when I saw his comment, I was shocked and I thought "I don't even said that" =.=
