One of the many reasons people lie is to avoid confrontation. It isn't necessarily to get one over anyone.
For the liars, avoidance or diffusing the situation is paramount. For whatever reason, the recipient of said lie tend to be much, much happier than if they were told the truth. This is the realm about lying, period!
To the OP, please don't despair. Your woman is simply trying her best to make you very, very happy.
Take for instance this exchange between a couple:
man: what happen to the stash we had in closet.
Woman: what stash? I don't know. "Yo no fui!"
would you've preferred the following instead?
man: what happen to the stash we had in closet.
Woman: Oh, yeah! I went shopping and gave some to my boyfriend. He was having cars problems!
===========
man: Where were you? I called on your cell and you did not pick up.
woman: I saw your missed call while I was in a meeting. Sorry, I couldn't pick up.
would you've preferred the following instead?
man: Where were you? I called on your cell and you did not pick up.
woman: I was playing hide the banana in the freight elevator with Mike. I was also unable to speak because he had his tongue in my mouth!
The length men and women go to make each other happy; priceless! :chinese:
