How many lies for you to mistrust someone?

Lets divide this in to two category(if you don’t mind):
-Small lies(stealing small amount of $ from your wallet/purse,making fake excuses for appointment,spreading uncertain gossip,etc).

-Big lies(Cheating behind you,or anything you consider as big lies).

So,how many lies will you take from each category to mistrust the liar?(please make it countable if you can)
Will you make any exception for this liar?(if the liar is your family member,superior,friends,etc)
