I cannot stress this enough: Be DIRECT and to the point.
If you're not a slave and don't really know what it's like being one, then chances are you probably don't know how slaves think and for that matter how slaves don't think.
Don't leave things to chance. If You're the kind of Master who thinks a slave is unequal, inferior and needs to live life according to Your rules and whims, then don't assume such a dependable slave is going to understand exactly what you mean by whatever generic term you've cleverly thought up to use. This is particular true of Aspergic slaves (approx. one-third of slaves) who find it harder to read the signals that most take for granted.
I'll update this with examples later.
