(Black biro on a 125mm x 75mm notecard)
Another image of an everyday phrase juxtaposed onto a comic-book style frame. In this case it's the kind of phrase that you hear on a bus when someone's on their phone. That's if they're not texting it.
If you're the type of person that does receive calls on buses in which you know you're going to have to say something like: "I'm on the bus...I'll be about ten minutes" and you hate doing that, then please feel free to attach the above image as a response to your worried little caller to save you the humiliation of saying it out loud or texting it.
