In the middle of a lecture

I'm in the middle of a lecture talking about Hospice Care by the Singapore Hospice Council.. I've been sitting in the lecture hall for past one hour and is bored to near death!! No doubt, This is a lecture i'm forced to attend.. I'm really bored now.. One of my friends just went off and the other is still enduring the torture with me.. I wonder what time can the naggy fellow end his speech and let us off.. Yeah!! He just said he has ended his speech and we are allowed to go soon!!! YEAH!! YEAH!!! :)
