I go up and down, And most associated with a fly I can close a gown And my teeth can bite, especially if you're a guy

I’m a fire with a home, In a wall I often stay. Families gather close to me On a cold and snowy day.

I'm a tower of hope, in a stormy sea, A warning or guide, for you and me, My light revolves, a steady friend, Illuminating the path, to journey's end.

A barber's quick move, without a flub, In the salon or the shrub. A swift, tiny cut, A sound, a soft tut, The work of a sharp little club.

You see me upon the ocean high, with white horses I ride. Foundations plunge down to the depths beneath but not to anchor me.
