THREE RHYMING RIDDLES

1)

Found in darkness, but never in light,

Present in daytime, but absent at night;

In dark and dreary, but not sunny or bright,

In the deepest of shadows we hide in plain sight.

2)

I can pull you off the floor,

But I can't push you through the door.

3)

A god, a planet, a measure of heat,

With winged sandals, a messenger fleet.
