- Ignore dust until it reaches letter-tracing levels.
- Use sleeve of top to make a token effort to wipe it away.
- Calculate the time it would take to get up from chair, walk over to cleaning supplies, and bring them back, as being greater than the time needed to calculate the time it would take and thus decide it would take too long.
- Decide that as dead skin accounts for 80% of all dust, it would be easier if humans had reptilian skin, which they would shed just once a year. Then realise it would not be ideal for the whole population of a country to shed their skin at the same time, as other countries might take advantage of the populations' indisposed state. Worse still, if the whole of Earth's population shed their skin at the same time aliens could invade.
- Forget about the dust; you've now got a brilliant new story featuring reptilian humans and alien invaders to write.
