Answer:
Good memory, skin like the sea. A great beast I am, yet vermin frightens me. What am I?
I can be long or short. I can be grown or bought. I can be painted or left bare. My tip can be round or square. (one word)
Before I grow I'm small. When I'm old I grow tall. When I die I give a mighty fall.
I am always coming but I never arrive. What am I?
I go up and I go down, towards the sky and the ground. Iβm present and past tense too, letβs go for a ride, me and you. What am I?
I will disappear every time you say my name.
