Why do I Have to Listen to Your Inane Gibbering?

Why do I Have to Listen to Your Inane Gibbering?
(Pointless Poetry from the Bus Seat #1)

There's a chap who sits beside me chatting with his friend called Sara
And she's off to Boots in Sherwood to purchase some new mascara
Then I think it's rather fortunate her parents named her Sara
'Cos I cannot find another word that rhymes well with mascara.

Sara's off soon to South Africa to see her friend Janine
Where she lives with wealthy parents and is treated like a queen
I imagine such a life of money, polo, sun and chicks
Then I realise that Boots is closed 'cos now it's half past six.
