This story was in one of my old middle school literature textbooks. I starts with a girl who along with the rest of her society is all excited to meet the aliens who have just made contact. The aliens finally land and the girl remarks right at the end that the aliens are similar to her but they only have hair on their heads instead of all over (the aliens are us).
I believe this is "Zoo" by Edward D. Hoch.
The story first appeared in the June 1958 issue of Fantastic Universe. It can be read here.
The story begins with children and adults, boys and girls, men and women, excited for the aliens to arrive.
The children were always good during the month of August, especially when it began to get near the twenty-third. It was on this day that the great silver spaceship carrying Professor Hugo’s Interplanetary Zoo settled down for its annual six-hour visit to the Chicago area.
Before daybreak the crowds would form, long lines of children and adults both, each one clutching his or her dollar, and waiting with wonderment to see what race of strange creatures the Professor had brought this year.
After everyone has seen the strange horse-spider aliens which look like horses, but run up walls like spiders, Professor Hugo and the aliens leave.
He waved farewell to them, and as the ship rose from the ground the Earth peoples agreed that this had been the very best Zoo yet....
Later, having completed visits to various worlds, the aliens return to their home planet. A she-creature greets her returning mate and offspring. They tell her they enjoyed all the worlds they visited, one in particular.
The little one ran up the wall of the cave. "On the place called Earth it was the best. The creatures there wear garments over their skins, and they walk on two legs.”
"But isn’t it dangerous?” asked the she-creature.
"No,” her mate answered. "There are bars to protect us from them. We remain right in the ship. Next time you must come with us. It is well worth the nineteen commocs it costs.”
And the little one nodded. "It was the very best Zoo ever....”
Other than one easily misremembered specific detail, the alien child at the end mentions clothes instead of hair, this story matches the description.
This is one of Hoch's most reprinted stories. I recognized it right away, but the definitive clue for me is the fact that OP read it in a school textbook. That's how I first discovered the story back in the 1980s.
Here are two pages from the Edward D. Hoch Bibliography which shows the publication history for this particular story. It has been reprinted dozens of times, about half of which are in various school textbooks and educational material.
