Event, which will require you to, er ... invent.
This month your character will be speaking in rhyme. All the time. Any form of rhyme will do; limericks, sonnets, and couplets too, sensical or nonsensical, it's all up to you!
The characters will feel a compulsion to speak this way. Night and day. As usual, normal Margate residents will not notice anything odd, unless the rhyming gets particularly bizarre, then you can decide whether or not they give it a nod.
The challenge is part of the fun. Have a good one!
The tag is "rhyme." Er ... lime. *nods* *eats cod*
