Sometimes there just aren't any questions worth answering. You must have had the same feeling yourself at one time or another.
same feeling here..
I have checked thoroughly and I'm only one of them if I either don't understand the question or feel I have no experience to be able to give a decent answer. EG: I just read your question about 'why we do not help homeless children when we come across them, but I haven't actually come across any homeless children.' I'll be sure to come back and reply though when it happens! :)
i do it sometimes
I review all the question but do not reply to questions from people underage. They don't listen or understand replies.
