Answer:
From house to house I go, sometimes narrow, sometimes wide. Whether there's rain or snow, I always stay outside. What am I?
I am a way to say goodbye to your sweetheart
I am a house with two occupants sometimes one rarely three. Break the walls eat the boarders then throw away me.
I come without being fetched at night, hide away as soon as daylight strikes. Although I may look small, I am much mightier than what you can imagine. What am I?
Six legs two heads two hands one long nose. Yet I use only four legs Wherever I go.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
