not really... its easier to say hello.. but i notice that few people doesn't care to bid goodbye at all.
they just disappear ! i don't know why it's hard for some to type the three letter word B-Y-E
as for me .. i find it necessary to at least say "bye" just to end the conversation
rather than just logging out without saying anything and leaving the other party hanging in the middle of an ongoing conversation ................ so rude!! and letting him/her waiting for response ? !
unless he is a nonsense talker - so its ok to ignore... lol
or maybe thats how it is these days.... maybe .... i am not just updated
