A girl I used to work with (she was my boss) years ago always used say "At the end of the day..."
I took her to task over it because it was cover for "I know it's wrong, but that's what my boss wants... why can't you just shut up and do it wrong?"
She even agreed with me... "I know exactly what you mean, but, at the end of the day.... oh my! I do say it a lot don't I?"
We both fell about laughing. She wouldn't bluddy go out with me though :lol:
Sadly, I use at least one of the others in speech ("To be honest..."), but I have been trying to phase it out recently.
There's another phrase I use a lot at work: "We're f***ed", as in "At the end of the day, if we were being totally honest with ourselves, we're f***ed..."
