And also...why are they so damn depressed on beautiful, sunny days???

This isn't always true, but the reason for it has to do with high pressure and low pressure systems. Air flows from areas of high pressure to areas of low pressure in the atmosphere, creating wind. Low pressure systems typically develop because the air is very moist, and clouds are forming through condensation, which actually serves to release more heat into the air and cause it to rise, creating an area of low pressure. So the air around it starts to rush in, catch some moisture from whatever's causing the humidity, condense out some clouds, and rise some more. As air rises, it cools again (a process called adiabatic cooling), and condenses even more clouds. It's a vicious cycle, and it's how storms are born. So that's why flags get excited before storms. If there is an area of high pressure above you, there isn't a bunch or air rushing in, in fact, the air just kind of sits and gradually decends in the atmosphere. Since the air is not rising but actually sinking, it's not making clouds, so you get fair skies. Flags don't much care for sunshine; they like wind.

It all has to do with the generation of wind coming from the south due to the anti clock wise direction in which the low pressure is producing,as the air is unstable,due to a more favorable condition for thunder storms,as the system wines up and moves to the north and east.
On a calm day there is no real disturbance,as a high pressure system would be in charge,on a more broader area,as cool air in the upper atmosphere sinks.
Love your expression,though!

May be they are storm flags. You know the red ones with the black square indicating storms to boaters. One for severe storm and 2 for hurricane.
I agree with you, being a sailor, when the flags point up there is alot of wind, and when they are hanging limply, there is no wind for sailing. Must be they are excited about sailing.

Flags are not alive, so they are neither excited nor depressed. Storms are associated with low pressure zones, which generate wind. Hot days are usually associated with higher pressures and little wind.

its because they like storms as much as humans.
