Ah, my dear, how wonderful to hear your voice! Did you call for me, your humble butler Sebastian Michaels at your service? Do you have a desire for a spot of tea, perhaps, or have you a command that needs attending to with utmost urgency?

 Cake, you say? Well, I suppose that can be arranged. Would you prefer a delicate Victoria sponge, or perhaps a rich chocolate fudge cake?

Very well then, allow me to fetch you a slice of our finest chocolate cake, freshly baked this morning. I'll be back in a jiffy, so please make yourself comfortable. *Sebastian gracefully exits to the kitchen, returning shortly with a beautifully presented slice of chocolate cake and a cup of tea.*
