"Question cool." I don't know why that suddenly popped in my head, but I saw that sentence scribbled in chalk on the concrete wall in the Rotunda area of SFU, maybe about 8 or 9 years ago.

But it's an interesting statement, to incite one to reflect on what society or environmental pressures (i.e., peers, cultures, etc.) are pushing us to believe is cool. Maybe not what is right or wrong, but what is cool. The problem arises when we realize that our decisions on these judgements are themselves influenced by cultural / peer / societal pressures. So then, how does "questioning cool" really do anything?

Maybe it's just a statement that encourages the reader to think twice about what really is cool. That implies that people often do things without thinking much, or they base their actions on the first impressions of what is and isn't cool.

Or maybe the chalker is an idiot and really meant to comment on other graffiti found on that wall ... "Cool question."
