Tell Me How?

Oh, dear little swallow flying high up in the sky,

How do you find your way I wonder, when do you take a rest and sit by?

Don't you ever lose your way in the clouds, oh my it's so confusing!

 How do you reach your nest? tell me the truth it keeps me amusing.

On the roads in the sky, I wonder if there are signals any,

Are there red yellow and green lights, or you need to follow many?

Are there any blunders or collisions in your way, as flying with you are so many fellows,

We humans have never understood, we just keep admiring the beautiful evening sight from below.

One last question baby swallow, I have for you,

If you forget your way back home do you get help up there too?

Do you also accept a kind helping hand to you which lends?

Do they offer sweets and biscuits to calm you and drop you back home, like down here we have police friends?
