Types of IM users I hate dislike who irritates me

1. Those who starts a convo with a "hihi"
   

2. Those who sends me "hihi" or nudge or buzz every 10 secs I did not reply

3. Those who adds a "haha" (anywhere) in an ABSOLUTELY-nothing-to-laugh-about convo

4. Those who totally ignores my "Busy" status and starts to chat about the weather, my lunch, his sod life...
   

5. Those who asks about my interesting display name everytime I update
