i think that some do get upset and leave over comments made by others or they just decide to hover in the background without posting. it's very easy when writing replies to posts to say the wrong thing, i have written replies sometimes with the best of intentions and when i've posted it and read it back i've been horrified that it can sound mean spirited or even nasty, i've never meant to offend but sometimes we post in haste and regret what we say afterwards. i think there are very few on here and other boards who go out of their way to upset others, most have there heart in the right place,
