I'm thinking about stealing my cousins Legos.
Why do you want to steal your cousin's legos?
That child has an endless supply of legos
Your cousin might have more legos than he needs but it would still be wrong for you to steal them. If you want legos then you should buy your own.
Err, it's not like I stole them yet or anything.
But you're thinking about it and regardless of the amount he his, it's still stealing, which is wrong.
