I think she was just a bit liberal with the truth.
for instance - I am sure Mrs S's bra may originally have been white. However it has probably got covered in foundation or fake tan, or been in a wash with turdy-coloured items, or she may have had a chocolate frenzy because it was 'that' time of her month.
so therefore Sqad - it was only a white lie and from that I must deduce that she is not having an affair. OK ?!!
