Am I...?

Am I a bad-weather-bringer???

Recently, when I go for shopping, every time it starts to rain and I get soaked on my way back home. And then it stops raining after I get home. Mmmmm... Something is wrong. I think I used to be a fine-weather-bringer. Are the symptoms of the bad weather bringer spread easily from person-to-person? The big mouse is definitely the latter...

Well, whatever...
