Stepping outside, seeing the rain and wishing I could shout Clear Skies and make the bad weather go away.
...or, when - after an unusual cold and rainy summer, the evenings finally are getting nice and warm, and you should sit on the porch, drinking a glass of whatever you prefer, but you wish it was cold and rainy, so you could stay inside and play Skyrim instead. (I realize some of you don't see the issue here, but where I live it's mandatory to Enjoy The Few Warm Summer Days We Actually Have and DAMN you if you don't! We are a bit obsessed with nice weather here...)
So, me preferring staying inside to play a game instead of being outside is a sign something's not right.
