If you’re just starting or don’t know the other person, let’s suppose to just begin with a formal “Hi”. But if you have talked for about 3-4 times, start next with asking any question you prefer or, something like “How was your day?” or “Was the day interesting without me?” usually works out.

Some attractive lines to begin a chat would be, “Though it’s none of my business, but I’m just curious to say a hi” or it could be more simpler like: I don’t remember exactly but I know you somehow, have we met earlier? The person you’re chatting with will remember and definitely revert back either in a positive manner or by blocking you, well some things totally depend on what you are. Still you should always know compliments for girls and disturb that busiest person in this world for a minute to say “Hi” and make ¡t interesting.
