Three Hypothetical Patterns about the Past

All three are grammatically correct. I would use the first and prefer the first because it’s the shortest. A good rule of thumb is to use as few words as possible, every word needs to add something, if it doesn’t, leave it out.

Having said that I would add can after still, so it says I still can remember the wedding, because that sounds more natural.

As far as grammatical concerns, they’re all acceptable. I’d choose #1 because it’s the most succinct as well as being clear. No one would raise an eyebrow with any of the choices.

{edit: Izzy and I agree}

welcome back, shengliver.

i am equally amazed that you found your way back here...

We often do.

I had trouble reposting the reply after I deleted it. I was warned that I was doing a duplicate post. Is it a bug of the site? Let me see if it will work by adding some words.

Thank you all for your replies.

One thing that still baffles me is that you Americans do not make a distinction between “happened” and “had happened”. One is in the past tense; the other in the past perfect tense. Here in China most of my colleagues (I am a teacher of English incidentally) thought that “had happened” is more reasonable since the sentence is a hypothesis about the past. We normally employ the simple past tense to talk about a hypothesis about the present. Compare the following 2 examples.

I wish I were a teenager now. (I am not a teenager.)
I wish I had married my high school sweetheart. (I did not marry her.)

Could you guys shed light on my bafflement? Thanks.

Thank Goodness, it worked. Pardon me for the first paragraph, please.
