Are there two kinds of oatmeal? Huh!

Ever make cookies with oatmeal and they are wonderful and the next time they spread out all over the cookie sheet?  Problem solved!  There are two kinds of oatmeal:  Quick and Old Fashioned.  When making cookies, always use Quick.  It absorbs the butter and any other liquid.  The Old Fashioned kind would take too long to absorb liquid and the cookies would already have been in the oven the required time.  Who would have thought oatmeal had so much character?
