I have a bright future

This really fills me with hope. It just reminds me how far we've come as a race. The puns humans come up with now are so awe-inspiring.

My phone screen is brighter than my future

My future is kinda bright but as soon as I walk outside the sun ruins it all?
Yeah that sounds about right

This means that his future is as bright as it can be, and that there is a limit on how bright you can be, this is the kind of thinking you have if you're closed minded.
