This is a large fault of mine, and I often ask myself similar questions. I believe the motive of this question (and you creating a Tumblr account) was to get me to respond to your email, and to that degree you have succeeded. (check your inbox)
I think that generally I am most likely to respond to things if I am capable of doing so as soon as I receive them. Your email (if I remember correctly) came as I was driving from St. Louis to Valparaiso. I received it on my iPhone and looked at it (dangerously), but decided (wisely) that I could not diagnose your problem or respond to your email while on the road, especially since it is now against the law in Illinois to do so, and for good reason.
When I got to my laptop back in Valparaiso, I checked my email, and since yours was marked as “read” I had forgotten about it, and did not look at it again.
This message, however, was received when I was in class with a computer in front of me. The class is on “blogging and web design” so being on a blog site is perfectly normal behavior. Since I am in front of a computer, I was also able to check my email, figure out the answer to your initial query and respond to it.
Read in to this what you may.
