For iPhone users, is it possible that you type a text, but forget to send it and not notice?

Like I use galaxy and if I type something and don't send it, it'll show "draft" in the text messages home page. Like it's obvious when I wrote something that I forgot to send. Is it similar to see this using an iPhone, or is it not possible?

There isn't a Draft box as such but the message doesn't disappear in the message field.
