Get key or talk to Conchita.

I am totally stuck in this game!
I can't get past the bit where I see Conchita with the vacuum cleaner and a key on the floor But can't get it or talk to her.
I've spoken to the hotdog seller and he mentions her, but I can't go any further.
Please help!!
Thanks.

You have to solve the crisis between the hot-dog seller and Conchita - she wants him to propose to her.

I solved it a while ago.
I just hadn't noticed the 'green text' words to click on!
Thanks anyway.
