I still don't understand,how did Rachel find out that Ross like her,i know that Chandler 说 something about a crystal 鸭 that Ross gave Carol 或者 something.i don't get it that Rachel was like "what oh my god"i don't understand how see found out.

Rachel: Oh... [opens it]... [sees the brooch] Oh my God. He remembered.
Phoebe: Remembered what?
Rachel: It was like months ago. We were walking 由 this antique store, and I saw this pin in the window, and I told him it was just like one my grandmother had when I was a little girl. Oh! I can't believe he remembered!
Chandler: Well, sure, but can 你 play it on a plane? [pats his Travel Scrabble game]
Phoebe: Oh, it's so pretty. This must have cost him a fortune.
Monica: I can't believe he did this.
Chandler: Come on, Ross? Remember back in college, when he fell in 爱情 with Carol and bought her that ridiculously expensive crystal duck?

Now that you've seen what has been said, let's explain. Phoebe had 评论 that it must have cost him a fortune to buy the precious brooch for Rachel right? And Monica couldn't believe that he would do that either. In Ross' defense, Chandler retorted to them that it wasn't a big deal because he did the same thing when he was IN 爱情 WITH CAROL. The line in bold practically told Rachel that Ross was in 爱情 with her. What Chandler was trying to prove was that what he had gotten for Rachel wasn't a big deal because he was in 爱情 with her, but everyone else with the exception of Joey didn't know that. So to them two, it didn't seem like a big deal since they knew he loved her. But thinking that your friend gets 你 a ridiculously expensive piece of jewelry, that's something 你 can't really fit together, because it doesn't make sense of why he and 或者 she would do that.

But the point Chandler was trying to make was that it wasn't a big deal--in the process it revealed Ross' 爱情 for Rachel. Did that make sense? If not, send a personal message so I can break things down a bit more. :)

Ross gets her something expensive for her birthday and Monica's like 'I can't believe he did this' that's when Chandler says when Ross fell in 爱情 with Carol he bought her an expensive gift. Then Rachel pretty much guesses.

Well, in the scene Rachel got a present from ross, a special brooch that look like the one her grandmother had and rachels like "how sweet...he remembers...i told him once i wanted that" monika is stunnded and can´t believe he did buy her such a thing so chandler jumps in and tells everyone that as ross was in 爱情 with this carol he did buy her all these ducks because ross knew she like them so much!
So he indicates that when Ross is in 爱情 whith a women he gets her stuff that she adores so she can be happy. Rachel gets the hint and finally knows.

Me too...

Well Chandler 说 to Rachel when Rachel got a very expensive brooch for her birthday that "When Ross fell in 爱情 with Carol, he bought her any expensive gift", Which means really that is Ross falls in 爱情 with a girl, he buys them expensive gifts. Which explains that Ross fell in 爱情 with Rachel.

Ross gave Rachel something really expensive and everyone else couldnt believe how expensive it was for just a friend to give to a friend but chandler says something like " oh come on guys, remember when ross was in 爱情 with carol he brought her that really expensive crystal duck."so rachel heard the 爱情 part and found out that ross is in 爱情 with her. Hope this Helps ;)

well see,He bought Carol a cristal 鸭 because he liked her and now he bought her tahat gift because he likes her....i hope u undersand a bit now....
