Here's a list of such things (not created by me), some serious, sometimes cynical, sometimes a white lie, sometimes covering their butt:
1. It wasn’t me! – Because some things just aren’t worth taking credit for.
2. The table will be ready in 5 minutes. – Because it sounds a lot better than 15 minutes.
3. Oh, yeah. That makes sense. – Because option B involves admitting that I am clueless.
4. Thank you so much! I just love it! – Because telling someone that their gift sucked would make me look like an insensitive jerk.
5. Yeah, you look great in that dress. – Because it’s better than being slapped.
6. Oh, things would have been different if I was there! – Because I’m Superman and I can always make a difference… or at least that’s how I want others to perceive of me.
7. No, officer… I have no idea how fast I was going. – Because claiming ignorance is sometimes better than admitting to insubordination.
8. I’m 29. – Because 29 is like 20 years younger than 30.
9. Yeah, I’ll start working on that ASAP! – Because telling you I have 10 things to do first would just irritate you.
10. Yes, John was with me last night. – Because that’s what friends do… we agree and ask questions later.
11. My resume is 5 pages long for a good reason. – Because I’m darn good at bullshittin’!
12. Man, that sucker was 10 feet long! – Because anything less would be boring.
13. Yeah, I was a badass on my high school football team! – Because I want to be seen by others in an even stronger light than I see myself.
14. I’m 21, 6’5, with a muscular build. – Because you can’t see me in this online chat room… ha ha!
15. I thought I already sent that email out. I’m sure I did. – Because telling you that it was a low priority and I forgot would probably hurt our relationship.
