Drink the soda first

We went to see Tangled today at the movie theater.

On the way in, with our ticket, Grace got a coupon for a free small soda.

She got a Diet Coke. She always gets a Diet Coke when she is allowed soda.

As she sits in the theater, drinking it sip by sip, she looks at me.

"Mom, I'm pretty sure that this isn't Diet Coke."

I quickly take a sip, but now my heart is racing and I am thinking -

'Penny, the one flippin time you don't taste her soda first!!!!!'

and I cannot decide if it's real Coke or diet Coke, cause I never drink Coke and now, I cannot even taste it if it's gasoline cause my brain is trying to do the math of 5 minutes of drinking regular Coke...

I have my other daughter taste it. She doesn't think it tastes like Diet Coke.

I literally walk as fast as humanly possible with a 3/4 full cup of soda to the concession stand.

'Uh, I think you gave my daughter regular Coke when she asked for Diet Coke."

"Oh yeah, I think I did" - she actually tells me she knew she made a mistake!

I don't know whether to laugh or cry.

'Cause my daughter has Type 1 diabetes and this could have gone REALLY wrong if she drank all of this Coke."

I am met with blank stares and complete silence. 

Lesson noted - always, always, taste test the soda when it's served by someone else.
