It appears that you marked your responses "Off Topic", therefore they are displayed "collapsed" -- clicking the little "+" (plus sign) at the upper-right portion of the post will display the message.
Many thanks for your kind advice.I was not aware of the requirement to click on the (+) sign.
However, as my last comment was not shown as usual, no comments have been received.That means the interested readers are unaware of this requirement too.
Hope it is clear now to every one.
Repeated thanks and kindest regards for your valued cooperation and understanding.
OK, now I see what you are saying. Comments get minimized when they are voted as "Off-topic". This happens for one of two reasons. Either the commenter toggles the "Off-topic" box before posting the message (see image below) or the user community votes that a particular comment is off-topic. In the case of your posts Hammamy, your comments were self-selected as off-topic. You probably did so mistakenly.
