apostrophe to make 'don't'. So your sentence should read:
Mary: Good, now you feel very happy, don't you?

The BBC Learning English community is reinforced beyond the blogs and comments pages. Learners are at the forefront in many programmes. For example, Grammar Challenge and Talk about English (see the Talk about English webcast Archive) feature real learners and are recorded on location in language schools; in addition, there is a Meet the team [http://www.bbc.co.uk/worldservice/learningenglish/radio/specials/1012_LEteam/p page on which learners can find out about the BBC Learning English staff: Learners can (and frequently do) use the Contact us page to e-mail us. Learner of the Week [http://www.bbc.co.uk/worldservice/learningenglish/communicate/] is a permanent link on the BBC Learning English homepage. There is a dedicated area of the site where many of these features are gathered together: This area is entitled Communicate and is central to the continued success of BBC Learning English (see Figure 4).
