As we enter the swimming class we go to the locker rooms. I am alone here because I am the only boy in this school. I change quick, there I notice how skinny I am now, and go to the pool.

Ava: 6'5, 150 pounds

As the girls enter Ava seems shorter yet again but at the same time stronger than before.

As I was concentrated on Ava suddenly I've been lifted up

"Surprise attack!!!" Anna says and thought me to the pool.

"That's not fair!" I say when I resurfaced. The others just laughing.

Ava: 6'4, 148 pounds

When I got out off the pool I saw Ava shrink a little, around 1". The Ashley and Maria start gossiping about Ava's change. How can they notice her change and not mine? Maybe it has to do something about that rock.

"Ladies and Davey, now we might make a girl's polo team, so everyone, but Davey to the pool!" The coach says and they obey.

"First, swim from side to side." See says. They do the same exercise for the next 10 minutes. They were extremely slow and uncoordinated.

"Everyone, this was just sad! For the rest of the hour just play at the pool" says sad and goes to her office.

Ava: 6'3, 146 pounds

"Hey girls, I have a funny idea!" I say

"What??" Anna says besides me.

"Let's measure our height to the measure wall!" I say. Everyone is laughing and Ava is a little confused by my suggestion, but everyone agrees.

Then we start with Himiko

"You are just 4'11 tall" Ava says.

"Damit, I thought, I would be taller by now" says laughing.

"Next you Davey." Anna says and push me to wall.

"You are 5'3 tall, just like the average girl" Ashley says and we all laughed.

Ava: 6'2, 143 pounds

"I'm Next!" Maria says.

"You are 5'5 tall" Ava says. Next we measure Ashley, Naomi and Diana, who all are 5'7 on the dot.

Ava: 6'1, 140 pounds

Next we measure my girlfriend who is 5'10 tall, oh my girl is 7 inches taller than me!

Ava: 6'0, 137 pounds.

"And finally our ex-giant Ava!"I say and everyone laughs. Ava is worried.

"Maybe I shrunk a bit but I am still the tallest one in the room" Ava says.

"To the wall"Ashley says and we push her.

Ava: 5'11, 134 pounds.

"You shrunk a foot, you are 5'11 tall!" Anna says and everyone is laughing, but Ava is shocked. She is pretty much as tall as Anna.

Ava: 5'09, 129 pounds.

"My mistake, you are just 5'9 tall" Anna says and put Ava at the head.

Then the bell rings and we go for break
