Well, first of all, I feel a little embarrassed to say that you all had much sweeter spirits than I did about my blog etiquette question from a few weeks ago! I very wrongly assumed the worst, instead of assuming that she had tried to mail my package and something had gone wrong. Thanks to you guys, I had a major change of heart.
So, I e-mailed her today, and guess what?! She DID mail my package, except she accidentally sent it to the wrong winner! (She had two giveaways that day on her site.) Somehow she put my name on the other girl's address, and the other girl never contacted her to say she'd won two prizes instead of one.
The "hostess" told me that she'd considered contacting me earlier to see if I liked my gifts, but she didn't want to seem annoying. She apologized and said that she will definitely send out my prizes.
This was a good lesson for me, both in blog etiquette and as a reminder to not assume the worst in others but to assume the best instead. Thank you for the gentle reminder that you all gave me without realizing it!
