The answer to your question is certainly No. The main reason what I feel is that even if you are very close to your chat friend, you will never ever come to know his/her emotions. For example, if your chat friend whom you trust very much decides to play a prank and makes an emotional statement, you may go with that topic without noticing the fact that he/she is enjoying the fact that you fallen for their prank. Chatting has always been considered as a bad world. Their have been many abduction cases, murders, etc only because of meeting of unknown people through chat. In case you know the chatting person in reality like you have met him/her or he/she is an old friend then there should not be any issues. After all every relation is based on a basic funda called trust and it is present in a very low percentage while chatting to unknown people. Be careful !!!
