Dear....
It's lunch time...
I'm sure you must be very hungry right now...
You didn't had anything for breakfast this morning right?
You are having a meeting in the afternoon...
So shall we go now?
It's getting late and it will be very rush for you if we delay any longer...
I don't want to jeopardize your stomach with any uncomfortable feeling...
And you need to rest for awhile before you go off for your meeting...
You've been caught in your work since morning without any break...
So it is the best we go for lunch now and get back as soon as we are done to rest ok?
