Did I ever tell you I dislike getting baked goods as a gift?
You have a problem with cupcakes???
I feel guilty when I think how much time that they spent on me.
We're all connected to other humans, and they are showing you that you are important part of their social circle. You should be flattered and happy that someone cares for you that much. If they selflessly spent time and effort to make you homemade sweets, you should be grateful that they love you so much!
I guess I'm also a little jealous of people who are such good cooks.
You can always learn to bake. You should be grateful that they put the time and effort into bringing something delightful into your life. Why invite them over for lunch and a baking lesson?
