Geo-math-ry Dash

Always greatly indulged in playing great games,
But when I sense danger, I switch to work –
To stop the risk of going up in flames,
To prevent my Mum from going berserk.
Slowly but surely I make awesome progress,
But sometimes I can forget to alternate.
When she comes back I will need to impress,
So my judgement has to be accurate.
I now know that I should devote time to research
So Mum thinks that I've been revising all this time.
Anyway, she re-opens tabs of games in search
Of the games she's seen me play in the meantime
Unfortunately, in the end, she distrusted
Her son that was distracted – and busted.
