Hi and Hello
The first words you always say to a stranger,friend or potential lover makes you wonder if there is some universal code of conduct for first encounters. Remember old alien movies where the aliens are always like we come in peace or take me to your leader. Even aliens care about first impressions, they wouldn't want us humans thinking they fly around the universe with bad manners.
The real question is why try so hard to get that awesome first impression only to fuck everything up as you go on. You start a race only to trip yourself half way but then again without that moment you might not have a race to run.
Dont judge a book by its cover, greatest lie ever told. If opinions were swords our blades would always be unsheathed ever ready for strangers way before the hi and hellos ever drop.
I would never blame anyone for lying on the first day after all the rest of the friendship is to get to know the truth. Keep your hi and your hello close by. You never know when you might need to start up a conversation.
