En route to success, I block your way. Perhaps right now, Telling 'R' from 'A'

Man, what a ring that sure is. It's... not made of solid material?

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.
