For the longest time I have always had difficulty finding the words to say, especially in response to people. I don't know why this is so, maybe it's my perfectionist nature or something like that. Whatever the cause I just struggle with finding the right words to say. I have found that I have gotten better with time and practice. That being said if I don't respond to a comment, please don't feel like I didn't like it. I greatly enjoy comments, I just didn't know what to say.
