Cloudy day

When I look outside the window, the first thing catching my eyes is that grey white cloudy sky. It's nothing special or should be surprised, coz yesterday was sunny. No any weather could stay long in San Francisco, know why? cuz the wind would carry the clouds and pollution and all down to Oakland, so most of time you could see a dark cloud on the top of Oakland........I still remembered that the whole class was laughing out loud like crazy when they told by the teacher.....you should see my expression......what a bunch of shameless seniors and juniors..........
