A question ????????

[Barb_D]

Surely I am not the only native speaker who finds this rule about never using object's object over-applied.

There are absolutely times when you can use the possessive for a non-human element.

The building's main entrance is closed, so I'll meet you at the side door.
This summer will be my town's 250th anniversary.
Look at this table - I like it better. See, the legs on that table are plain and blocky, but this table's legs are carved and pretty.

I understand that learners learn a rule and THEN learn the exceptions, but this strong empahasis on NEVER using the 's for an object is not, in my opinion, a reflection of the actual use of the lanague.

tedtmc is right. Objects don't have possesions but only humans so never say "today's lecture, sun's rays, PSP's box, etc.". Use "object of the object".

I think you are not right, i can easily use objects for possesive nouns and not only living being. I can give a dozen of examples: "Today's performance" "the world's biggest castle" etc.
Its not so common, though.

In my part of the world, it is extremely common. I agree with Barb. There is too much emphasis on this "rule".

I WANT TO ASK YOU
WHEN WE CAN DELETE POSSESSIVE ('S) ?
AND I WANT TO ASK IF WE CAN SAY ( THE KITCHEN WINDOW )
INSTEAD OF (THE kitchen's window)

and thanks a lot

Dectator, in your example phrase, the word kitchen functions as an adjective.
Adjectives do not take -'s, nouns do. In other words, the noun kitchen functions as an adjective here:

Ex: kitchen window [adjective + noun]

Test it
Q: What kind of window?
A: A kitchen window.

_______________
Traditionally, there were rules that stated you could not add -'s to nouns that represented non-living things. The most common example was

the table's leg <Modern English speakers use this>
the leg of the table .

Today's speakers, however, don't live in the past, and hence tend not to follow those rules.

Thanks for corrections. I typed it at a high speed.
I'm not sure about this one, though:

"dozen of examples" - Yahoo!7 Search Results

1 - 10 of about 849 for "dozen of examples"
1 - 10 of about 466,000 for "dozens of examples"
1 - 10 of about 92,000 for "a dozen examples"

Hm.

(The phrase "dozen of examples" in all its variants is apparently used to mean "twelve".)
