Alexa vs. the Instant-Dry Swimsuit

Today was pajama day at the kids' school, and it was also swim day for Alexa. The kids went to school in their PJs and had regular clothes packed to be changed into. However, both kids were still in their pajamas when I picked them up.

Me: "Alexa, did you swim today?"

Alexa: "Yes I did Mommy."

Me: "Hmm, really? Because you are still in your pajamas. And your towel and swimsuit are not wet."

Alexa: "I went swimming! For real, I did. They just dried."

Me: "Oh, well, I just have never seen a suit and towel dry this quickly."

Alexa: "Mommy, I'm not lying! They dried. A chemical made them dry so quickly."

[PS. I quietly asked her teacher and no, she did not swim today. She did lie. :)]
