Am thinking about YoMoJo's thread about her toddler chucking sweets on the floor in Sainsbury's as an example. It's been pointed out to her several times that SWBU, and she's had the good grace and humour to accept that she was in the wrong. Despite this, other posters just pile on and add to the kicking, making her bad day, and embarrassment about the whole episode just that bit crappier.
Read the thread before launching in with criticism - and if you don't have time, don't respond!!
