According the to Southend News Network, A school in the UK had to ban Valentines Day Cards after a 6 year old student allegedly gave his teacher a Valentines Day Card that said "He would plow her into next week". Okay where did he learn that from Mom and Dad? You might want to be a little more discrete about the things you say in front of this young man.
The student in question has been suspended until the school has a chance to investigate the incident further.
