Fat?

One of pupils in my P3 class came up to me the moment I stepped in and asked:

Pupil: Mrs Wong, why your stomach so big?
Me: I'm fat!
Pupil: You got so fat one meh?
Me: Yes... (Shakes head in disbelief)

Why would he look at my tummy? Kids these days... not concentrating on books but on teacher's tummies. Tsk tsk...
