Answer:
I am a way to say goodbye to your sweetheart
I can be winding and I can be straight. I can be smooth and I can be rough. Sometimes both. I start out black but fade to brown. My favorite colors are yellow and white and I love stripes and dashed lines.
I have a head and a tail but my eyes can never see my tail.
Soft, hairy, from door to door. I am the pet that always stays on the floor. What am I?
By Moon or by Sun I shall be found. Yet I am undone if there's no light around.
If itβs information you seek, come and see me. If itβs pairs of letters you need, I have consecutively three. What am I?
