I wanted to write to you to let you know about the thoughtfulness of your pupils today.I had collected my daughters (4&6) from Primary school, we entered Tulse Hill station from Avenue Road, my girls were ahead of me waiting at the bottom of the steps of platform 3. Approaching me were 2 girls in their own clothes who basically stopped me from passing, though I brushed pass and apologised for knocking one of their arms they followed me got in front again. I managed to get to my children, they then cornered my 6 year old who was crying, I pulled her away and we ran to the ticket office.The reason for this is there were 3 girls from your school. I have found this out by research, who were very considerate and polite and asked if my daughter and I were all alrightUnfortunately I was so shaken I did not ask their names, but they did then go to Platform 4. Young people are too often criticised, therefore I wanted to pass this onto you.
