I lied.

It has been quite a while since I lied to her. I don't even remember the last thing I lied about to her.

Whenever I see an argument about to happen, I have always been on the offensive. I have always tried to show my actions as an effect of some cause, but I never tried to cover up things I have done. However, this time I tried to evade the argument and I lied. I don't understand why I did that but my instant reaction was to cover it up. I did send her a solitary message admitting that I lied. Yet, I do not understand the reason for my initial and later reactions.
