What I had understood that verb attendre is not followed by any preposition….elle attendait de m’entendre…. Why are we using de here ?

I understand the literal meaning of this phrase but not really the sense of what she's saying.  Agreeing? disagreeing?

My dictionary defines "rayon" as a department within a store, not as an aisle (which it translates as "allée")

Are "en tout cas" and "en tous cas" both acceptable ways of spelling this to mean "in any case". This exercise only accepted the latter, but I thought the former was correct. 

Is ‘its been a long time since ‘ always followed by a verb in the negative? Some language sites seem to have sentences without a negative.

What is correct " tu achetes les chaussures" or " tu achetes des chaussures" 

Why does he switch from je to on?  There is no hint, up to that point, that he will be going with others.

Would you use "et" for numbers over 100 (e.g. 101, 201, 1001, etc.)?

Cent un, or cent et un, or cent-et-un?

Thank you for your help. 

The tittle of the passage is 'A quoi ça sert de trier ses déchets' is translated as what is the use of sorting our waste? Our=notre / nos? and ses = his / her / its? Please help understand if the translation is correct?
