Answer:
My tail is long my coat is brown I like the country I like the town. I can live in a house or live in a shed And I come out to play when you are in bed.
I live off of a busy street if you want you can stay for an hour or two but if you don't pay rent I'll tell on you.
My first is a heir; My second's a snare; my whole is the offspring of fancy; which I sent out of play upon Valentine's day As a token of love to my Nancy.
I carry you down a gentle stream.
I beam, I shine, I sparkle white. I'll brighten the day with a single light. I'll charm and enchant all. I'll bring the best in you all. What am I?
The answer I give is yes, but what I mean is no. What was the question?
