Hey, Mums.
Hello, Darling.
I'm going to Costco this week, if you need anything. (flimsy excuse to phone parents)
I'll let you know, Darling. Are you coming over today?
I hadn't really thought about it. (bare faced lie)
Why don't you come over for lunch? Or do you have something planned already?
No, err ... (pretends to think it over) ... Yes, okay, what sort of time?
Whenever you like, Darling. We'll eat about two.
Okay, Ciao Mums.
SORTED!
Oh, Mums, I nearly forgot ... can I bring a friend with a large collection of rustley silk items?
