Zack: She put the drops from the bottle on my back. I had to lie still while she did that. Then she did a little prick on each drop.

Zack: After awhile she looked at my skin to see if I got a red bump where each drop was. She measured the bumps. If the bump was big enough I may have an allergy.

Tina: So now you have red bumps on your back.

Zack: No, they're gone now.
