The bedroom door does have a lock on it, but it has never ever crossed my mind to lock it, given that i live in a quiet area inside a compound with 24 hour security. Outside on the balcony there is also large white sliding gates, which, if i had locked, then there is no way he would have got in. Having said this, i have never closed these and on no occasion has anyone ever suggested that i should lock then at night.

Sorry to hear this.

The school will use this against you though, but I still hope you can gain some recompense.
