... I completely eat the outside chocolate part of a Mars bar first before eating the caramel, then finally the chocolate nuget inside. Mmmm.
I always eat my favourite part of any food last, though. Regardless of what it is. Usually that means eating around the outside in a circle and working my way inwards.
I also eat candy by colours: least favourite to most favourite (last).
Geeze, I really am a "save the best for last" person.
I do all of these too. Except I don't like Mars bars, but I do it with other candy.
