How can I change the PowerShell prompt to show just the parent directory and current directory?

Question

I would like to shorten my PowerShell prompt so that it just shows the parent directory and the current directory. For example, if the pwd is

C:\\Users\\ndun

These other replies were much more involved. Even so, here's mine. If it's greater than 30 characters, we shorten the path. Done.

Function Prompt {
    If ("$($executionContext.SessionState.Path.CurrentLocation)>".Length -le 30) {
        "PS $($executionContext.SessionState.Path.CurrentLocation)$('>' * ($nestedPromptLevel + 1)) ";
    } Else {
        "PS ...\$(Split-Path -Path $executionContext.SessionState.Path.CurrentLocation -Leaf)$('>' * ($nestedPromptLevel + 1)) ";
    } # End If.
} # End Function: Prompt.
