Answer the question about text:

I do n't know how to describe the beauty of this weekend . I spent Friday night yelling over cheap martinis to a fellow journalism student about our future careers . We laughed , screamed , made passes at our waiter and nearly lost our voices . Saturday night my boyfriend and I drove out to the suburbs for my cousin 's post - wedding party . There , I got to see my mother , who has just returned from France , and a lot of family I have n't seen in a while .

Why would the narrator be happy to see their mother ?
Their mom had returned from a trip .
