     A primary school has banned Valentine's Day cards because of concerns that young pupils spend too much time talking about boyfriends and girlfriends.

     Ashcombe Primary School in WestonsuperMare, Somerset, has told parents that cards declaring love

can be "confusing" for children under the age of 11, who are still emotionally and socially developing.

     In his February newsletter (简讯), Peter Turner,head teacher, warned that any cards found in school

would be confiscated.

     He wrote, "We do not wish to see any Valentine's Day cards in school this year. Some children and

parents encourage a lot of talks about boyfriends and girlfriends."

      "We believe that such ideas should wait until children are mature enough emotionally and socially to

understand the commitment involved in having or being a boyfriend or girlfriend."

     Mr. Turner said any families wanting to support the Valentine's Day concept should send cards in the

post or deliver them to home addresses by hand.

     His views were supported by Ruth Rice, 46, who has twins Harriet and Olivia,9,at the school.

     She said, "Children at that age shouldn't really be thinking about Valentine's Day, and they should be

concentrating on their schoolwork."

      "They are at an age when they are easily influenced and most parents including myself are with

Mr. Turner."

      She added, "The cards caused too much competition. If someone gets a card and another doesn't then he will be disappointed."

      However, Rajeev Takyar, 40, who sells newspapers and has two children Jai, 11, and Aryan, 5, at the school, said he was "genuinely outraged".

     He said, "There are schools that have banned conkers (康克戏) and snowballs, and now Valentine's

Day cards."

      "I think banning the cards stops children from having social skills. How are they going to learn about relationships otherwise? It's ridiculous."

     Alec Suttenwood, founder of the AntiPolitical Correctness Group, said of the ban, "It's totally

ridiculous. Young children just send the cards to each other as friends and to their parents. It's just a bit of harmless fun. There is no difference between this and Mother's or Father's Day."
