No, you aren't crazy. It is in fact, NOT raining outside right now.
It's weird, especially considering the fact that it didn't rain all weekend either.
Considering the weather we've been "treated" to so far this year, this is pretty much the closest thing to a heatwave we're going to be experiencing for quite some time.
So do yourself a favor; Go outside, take a walk, ride a bike, have a drink on a terrasse, or whatever makes you happy. Just make sure make the most of the sunshine!
