Having said that
These days I hear people using "having said that" a lot. Having said that, most of that usage seems appropriate and correct. When you say something, and you want to contradict yourself in the next statement, you use having said that. Having said that, now I think it's not used for contradicting; its purpose is to soften your previous statement with some doubt and indecision. Having said that, I must concede that there might be other usages.
Having said all that, now I must record that for the second time I left the car keys inside and locked us out. Well.. the Advaith guy was here within an hour of us calling their helpline and opened the door within minutes with a simple what-old-timers-call scale (I've heard it being called "ruler" by some misinformed kids these days). Having said that, he did struggle a bit. I say that not because he really struggled but because I don't know how else I could've used having said that in the last sentence :P
