In this lesson there is an example of passer in passé compose using être:

Ma tante est passée par la boulangerie... 

and using avoir:

Nous avons passé une bonne semaine...

I can't see an explanation for this and I'm confused

Can I use "la fillette" instead of "la petite fille"?

vraiment ou vraiement?  I think it is vraiment -

I just wanted to say that the video in this lesson was super helpful. I struggled so much with this concept and now I get it right all the time. So, thank you!

Can I say "qui- sont-ce for saying who are they? 
who are they =qui sont-ce? 
they are my friends= Ce sont mes amis
