First think of the person who lives in disguise,
Who deals in secrets and tells naught but lies.
Next, tell me what's the last thing to mend,
The middle of middle and end of the end?
And finally give me the sound often heard
During the খুঁজুন for a hard-to-find word.
Now string them together, and answer me this,
Which creature would আপনি be unwilling to kiss?
