With regard to the 'sex with Heather' comment... I read an article in one of the US tabloids, Enquirer, World News, one of them...
In the last paragraph it said that Heather was bragging to her friends that she has been giving Paul the best sex he's ever had in his life.
I saw red when I read that! How inconsiderate to say such a thing. Her comment implies that the sex Paul had with Linda was 'lacking'.
I can see if she commented that sex with her was the best Paul had since Linda, but I thought the comment she made (if, in fact she did make it) was a slam to Linda.
