Teardrops are the imagery I've always heard, not pears. I think lots of folks associate rain with sadness and melancholy.

 

Rain makes me happy, like the tasty brioche bun whose shape they share.

 

I always thought they were 'molded' in that shape by the streamlines of the medium they are falling through.

But if they're not 'teardrop' shape, I guess I'm wrong.

I think they're only that shape just before they fall off an eyelash. They round out when falling. I'm sure they'd assume true raindrop shape if they fell far enough.

 

I hope this isn't off-topic for the discussion, since this is more about what happens when water hits rather than when it's falling, but I found this very interesting:

 

Maybe we think they are that shape from watching them run down windows...
