Habits - present continous vs present simple.

[kobeobie]

I am trying to understand why we sometimes choose to use present continuous rather than present simple to describe an habitual or repeated action.Please have a look at the sentences below:

She always smiles.

She is always smiling.

 

[miwalko]

The latter sentence expresses that the speaker is annoyed by her constant smiling (at least according to grammar books).

 

[kobeobie]

I also read that in a grammar book but I don't think that this is always the case.If someone were to say:

Little Susie is so cute,she's always smiling.

I wouldn't get the feeling that the speaker is annoyed by her constant smiling.

 

[miwalko]

Little Susie is so cute,she's always smiling.

Do (many) native speakers agree that this is a good sentence - as it is, with no further context, such as Little Susie is so cute,she's always smiling when I meet her?

I can't see anything wrong with the words. As far as the punctuation goes I would put either a dash or a full stop between "cute" and "She's".
