Ridiculous misguided gesture.
She cannot take it upon herself to do it on behalf of the comnunity because so many of them are distraught. Distraught because time and time again where migrant men are gathered in large numbers sex attacks have occurred. Crowborough, I've been to it on a number of occasions, is a small to moderate sized town of some 11,000 people who will have 600 young men accommodated in the barracks on the edge of town.
St Valentine, as mentioned up thread was a Christian saint. This day embedded in western culture where people send a card to their loved one or anonymously to a person they've set their sights on. Cards range from love and hearts to more suggestive content. Highly inappropriate and quite possibly amongst those men, some might understand the context of what the day represents culturally in the west.
So what are they, the men, supposed to make of cards on such a theme? delivered by children I believe 
Just wrong on so many levels.
