I would rather always have to announce myself when walking into a room, because it seems like it would draw less attention. I try to greet my teachers whenever I walk into their classrooms, so I think it would be fairly easy to tack on an extra sentence informing everyone of my presence. If I was in a professional setting, like a job interview, cartwheeling on my way out could hurt my chances of getting the job; and also be dangerous if I was wearing fancy clothes. Both scenarios are definitely out of my comfort zone, but I think the first option is better to just get over the embarrassment quickly.
