I'm not a "sugar" person. A bag of chocolate or sweets could sit unopened at my apt. for months (this requires no self-restraint). On my first birthday in Germany, everyone gave me sweets and chocolate. These remain unopened until 8 months later when I returned to the US and gave them to my family and friends. A bag of salty chips is a completely different story...*
With that said - on all recent trips, I somehow ended up at a cupcake shops. There is something about cupcakes that make them difficult to resist. The cupcakes (seen below) all received a 100% rating on the "yummy" scale.
