Darkangel, maybe you have just been believing what you said in the moment to be true ( as this is what you say ) and this can happen to all of us. Later we find out or get told that it wasnt or isnt so but we did believe it when we said it. It can be that our brain mess with us a little at that moment and we are not aware that what we said is not right or true. It has happened to me too sometimes and when I find out that what I said, ( for example giving information about something ) is not correct I feel I shouldnt have said what I said or think why did I say that. If this is the case with you there is always ok to say to them you thought you were right when you werent and just say sorry about that ( if they ask why you lied or said that ). Then good people and friends will understand.

Its something different to lie and be aware of it.
