Question: Following a previous discussion about **I would like** vs **I would have liked**, I have a similar question.

What is the difference between

> 
> I wanted to come to your party but I couldn't 
> 
> 
> I would have liked to come to your party but I couldn't.
> 
> 
>

Answer: 
I've answered essentially the same question over at english.stackexchange.com: [Why is “our today's meeting” wrong?](https://english.stackexchange.com/questions/251561/why-is-our-todays-meeting-wrong)

Usually, a noun phrase in English must have exactly one determiner: you can say "I drove this car" or "I drove my car", but not "I drove car" or "I drove this my car".

Certain nouns (such as plural nouns and proper nouns) don't need determiners: "I love bees", "I love milk", "I love Paris", "I love biology". But it's never acceptable for a noun phrase to have more than one determiner (with possible extremely rare exceptions).

"Our last week's meeting" is unacceptable because the noun phrase "meeting" has two determiners, "our" and "last week's". It would also be unacceptable to say "the today's meeting" or "our the meeting".

Here are some phrases which may *seem* to have multiple determiners, but don't actually:

* your father's home - this noun phrase has only one determiner, namely, "your father's". Meanwhile, the phrase "your father" is also a noun phrase which only has one determiner, namely, "your".
* the brass men's wristwatches - the determiner of this noun phrase is "the", and "brass" and "men's" are adjectives.
* an old people's home - the determiner of this noun phrase is "an". The phrase "old people's home" is an idiom which acts as a simple noun, even though it looks like it contains a determiner.
It's either: 

> 
> Last week's meeting
> 
> 
> 

or: 

> 
> Our meeting last week
> 
> 
> 

but I agree with your teacher that:

> 
> Our last week's meeting 
> 
> 
> 

sounds awkward and should probably be avoided.
