I have got the knack of sink/sunk etc. but I am not sure about sat/sitting or stood/standing.

Obviously 'I was sat sitting there' is an incorrect comedic phrase in the best Hilda Baker tradion but which is right, "I sat there" or "I was sitting there"?

Both sound OK to me and seem pretty interchangeable. Under which circumstances would you use one in preference to the other?

I am not sure if it is bad grammar or just bad but, to keep to the topic, the Turtles 'Elenore' takes some beating:-)

Elenore, gee I think you're swell
And you really do me well
You're my pride and joy, et cetera
Elenore, can I take the time
To ask you to speak your mind
Tell me that you love me better

In fairness, I do believe it was written as a spoof.

Cheers
