Thank for sharing your experience, Xiao Zhuang. I truly think that people involved in the discussion understood each other's good intention.
I always think if there is one in this forum who needs to learn that person is me. I am open to all criticism as I claimed before. If I argue over something I am not defending my problem. I just want to make myself understand better. I hope that people understand me.
I think that you were right. If people do not care about you they will not spend time to discuss with you. So I need to thank all who brought some thing up.
