Orh... good! Good! Make sure she doesn't place more food in
front of you so you won't feel guilty then you won't overeat!

As for me, I've learnt to just close one eye and walk away. I've
been leaving stuff half-eaten and what-not nowadays.
The minute I am full, I stop. (Unless it's my favourite,
die-die-must-finish kinda food!
) Also, I've been throwing away food like cookies and all that,
cause usually, I'll buy them, eat 3-4, then lose interest liao, and
then, they expire.
