One day, you see a fly.
The next day, you tell a lie.
On the third day, you're being sly.
The day after that, you're acting shy.
On the fifth day, you witness someone die.
The sixth day, you notice the weather was dry.
One day later, what is it that you finally decide to buy?
Written as a poem. Turned out like a riddle with no answer.
If there is, it'd be open up to viewer interpretation.
