Listen carefully. If they fool you ONCE, they will fool you twice and over and over and over again. Do not let this happen to you.
Here is the scoop. If you put a "chocolate chip" cookie in your mouth you must immediately make sure that the chocolate chips are truly chocolate. People (adults) like to fool you with healthy things like raisons. Not gonna fly here. If you are being tricked, promptly spit out every bit of what is in your mouth onto your clothing and the floor. Then smear it all over your shirt and stomp on the crumbs to make sure they are very fine and very hard to clean up. This will teach them to try tricking you again.
Once you know for sure that chocolate chips are present keep doing a fine chew just to make sure that there is nothing like nuts or something else posing as maybe white chocolate chips!
All success here. Proceed to finish the scrumptiousness.
