I realised that he was speaking to somebody, i did decide to knock how ever he carried on talking but then i heard a silence and he said 'hello' ... 'hello' (as to see who was knocking) but i wasn't brave enough to go inside... however they started with the conversation again. And with a result of this, i descided to no go in but to wait until they finished, yes i know i'm so stupid to have acted that way, but thats the way i felt and the need of reacted. I waited and waited i saw 2 teachers and a few pupils they spoke to me and i replyed back but when they went i carried on waiting, i did have that feeling to have given up and go away but i didnt dont know why but something made me stay... Eventually i got to the right time...
