Would you mind doing smth?

Thanks lads and gals,

I deem my query solved. You can proceed with your gramma dilemma or close the thread, I do not mind it.

Once again I do appreciate your help.

Cheers!

ok, if you have time, wipe the floor with me again and tell me why there is no 'have' betweetn the two underlined words :)

Ja tez mysle, ze 'have' powinno byc.

Just because we are the 'GRAMMA" police.
Przypominam, chociaz wiem, ze niektorzy to i tak to dobrze wiedza, ze mowi sie albo 'lads and lassies' albo 'guys and gals' - jedno jest BrE a drugie AmE...

So this is your cherry on the cake? Hope you didn't pull an all-nighter on this:)

But ok, you got me there, tough guy, and yes, 'have' should be there
but I skipped it and I shouldn't have. And the answer is simple, nobody's perfect.
It actually takes a lot for some people to admit they're wrong, so I'm liberated, haha.

Back to this simple tense in since-clauses.
It's only common sense to take your blinders off and always keep such details in mind while taking a grammar test where you know it's always safer to stick to conventions if you want to squeak through with a straight A.
