Help me!

I really need to meet with my mentor! Last week he told me that we'd meet on Thursday and he never showed up which is really strange because usually  I see him every week. The reason I need him is because I actually need to ask him for help with my presentation. He has been so great the whole project always there for me and not pushy at all ( which may not actually have been good) but now when need him he is missing. Come back Bowen, come back.
