[Sertius]

First of all the comment Luke made was about her and not to her and was to emphasise her lack of respect.

No one else in the house ever mentioned her BMI/weight/obesity although probably all of them had some thoughts about it.

No. The person who told her about her weight problem was her sister - face to face sort of.

Now either her sister:

1. Knew she was sensitive about her size but still wanted to hurt her feelings by telling her. She would have known how this would affect Becky and possibly ruin the rest of her time in there. Ergo her sister is not very nice towards her.

Or:

2. She knew it was of little importance to Becky and that she would not be overly offended by it but would milk the situation for all it is worth. Ergo no real offence only 'acting'.

You decide.......
