This is a multiple answer:-

a) I can tetch with the best of them when the mood takes me - I just had a sudden burst of patriotic fervour which started me fighting the War of Independence (and probably losing it ) all over again! No offence was intended, and apologies if any was taken.
b) I certainly don't wear Rhuby red slippers - the colo(u)r clashes with the burgundy of the whites of my eyes.
c) "'jamas"; "Jammies"; "Jim-Jams" are all fairly usual contractions over here.
