The old waiting game

I hope my boss has gone into the office today. I say this because I handed my notice in on Monday, leaving it in a prominent place over her keyboard today. I have received carbon copies of her emails today so either she has read it and isn't speaking to me, or she is working from home. Is she is at home, then that means I have to watch her reaction as she reads it and, as I detest confrontation, I will not look forward to it. It could indeed damage the working relationship however I hope that it won't.
