I, on the other hand, perceive rain differently. Rain (or a raining weather, not stormy) is romantic. I'm much of a homebody so when it rains, we all get stuck under one roof and you have no choice but stay in. So rain is a bonding moment. Rain equals hot beverages and warm talks. If you're with your boy/girlfriend, then it's more of cuddles and stuff. Nescafe moment. Exactly.
