Have you ever seen a UFO?

"Have you ever seen a UFO?"
Mom's been teaching her students about the present perfect in English grammar, and we've heard several of her students practice asking and answering this question several times already. Each time, we'd like to shout a resounding "YES! Right here at home!" 「我が家に変なやつがやってきたぞ！」

You see, last weekend, Dad took this "thing" out of a box and suddenly, IT CAME ALIVE! It's a saucer-shaped object with rotating wing-like brushes and made this loud whooshing noise as it scurried around the living room floor. It kept bumping into things too, and sucked up all the dirt and our hair on the floor. At first we thought it would play with us, but it just ignored us and went on its way. After a while Hop got frustrated and started yapping at it in a embarrassingly whimpy voice, but still the "thing" just carried on going and whooshing. Now it's a permanent member of our family, coming alive every morning and going back to sleep after an hour or so.


(We can't understand it, but Mom and Dad seemed very pleased to see this weird-looking UFO running around the house.　不思議でしょうがない…)
