Mark as Unread

Does anyone else have the problem of not being able to mark text messages as unread?

If you are going to ask me a question or otherwise send me something which requires follow-up on my part, please do not do it via text message.  Once I read it, I can't mark it as unread, and I can almost guarantee that I'll forget to do whatever it is you want.  That's one of the beauties of email - it can overwhelm me later with all the things I need to get back to!
