Help!: Mitering porcelain bullnose tiles

[stevesur]

I am tiling my bathroom walls with porcelain tile. Where the corners meet I am butting the tiles up at right angles. The grout will fill in where they meet. However the bullnose with it's round edge appears to need to be mitred or cut in a way for the round profile to meet in a way to look finished. Is it appropriate to just butt the bullnose tiles up at a right angle at the room corners to look finished (will the grout compensate?) Or should the bullnose tiles be beveled somehow?

They need to be scribed..

Dave, thanks for your prompt reply! I will scribe bullnose as suggested
