I have a little pool with two layers of wall around it. One white and soft and the other dark and hard. Amidst a light brown grassy lawn with an outline of a green grass.
I belong to everyone. Sometimes make you happy sometimes make you sad. I will never end until the day you do.
I am flora, not fauna. I am foliage, not trees. I am shrubbery, not grass. What am I?
Sometimes I fly as fast as the speed of light. Sometime I crawl as slow as a snail. Unknown until I am measured but you will certainly miss me when Iām gone.
What goes up and down stairs without moving?
A little house full of meat, no door to go in and eat.
