And oh, before i forget, today, during Flag raising a bird flew and banged onto a wall. Then everyone's like O.o and talking about the bird. Then I think that it's dead but guess what, after sometime, the bird managed to flew away! The whole school clapped, it's not dead! OMG is that bird determined :) I love that cute bird :)
