Me: Would you like a sandwich for tea ?
M-I-L: Oh not really. I don't really feel hungry yet.
Me: OK.
M-I-L: What time is it ?
Me: Ten to 6.
M-I-L: Is that the real time ?
Me: Yes.
Exasperated, I decided to spice things up a little...
Me: Well, of course, your body thinks it is ten to 5 which is probably why you're not hungry yet.
M-I-L: But what time is it really ?
Me: Time to pack up and for me to run you back home.
