Yes, I do tell lies, but perhaps what I just stated is a lie? Either way, I would be lying, I suppose.
But in all seriousness, as someone had stated earlier, it is human nature to lie. If you say that you do not lie, then you are lying. Everyone lies whether they figure they are doing so or not.
The real question is, Do you lie often? In which case, at times I do. Sometimes I lie on purpose, and other times, on accident. To tell you the truth, I do not keep track of things like that, so I could be lying right now without even knowing!
