Very good English. The tags seemed excellent and just as in spoken English. Only one point, I think some qualifier needs to be before 'parents' in the last sentence otherwise it seems out of place. I put 'our' before 'parents'. You could also say, maybe sarcastically, 'And don't shout at the parents, will you? or 'Don't shout at your parents, will you?' The sentence begins with 'and' and 'comes after having breakfast in the previous sentence so it seems quite homely and specific. A teacher might say, jokingly, to another teacher about parent-teacher meetings, 'And don't shout at parents, will you?' So the sentence is, as such, grammatically correct.
