Un(reason)able

I was on my way home after a long tutoring session when I spotted this advertising gem.

"Sometimes reason can't solve problem...
Let her go shopping alone,
Things will get better."

Ah, so that's the problem! I've been wasting all this time with words when my friends should just put a Visa in my hand.

Thanks Bangkok!

P.S. The advert was for a new condo... I can't see how that is even anywhere related.
