^ That's good tip. It's easier said than done though:-)
Yes, it is hard in the beginning. It takes some tries to get used to the awkwardness of it. But you get used to it, and then it becomes so easy! You just have to start.
I started doing this when I was 8 or 9 (Aunties prey on little kids- "so what is you're parents job, arghhhhhh). I wasn't perfect then, and I'd slip here and there- and my mother would give me a lecture on why I felt the need to answer that lady's question. So I guess having a mom helping me out there helped.
