Hermione tries to buy dress robes for Ron, but he's so tall that this feat is difficult. Not to mention Ron becomes jealous when he realises Crookshanks is getting a pair too. 

Harry dating Ginny has been a Weasley source of amusement for a long time... and sometimes when he's being teased, he's not even there to stand up for himself.

Ron wakes up feeling hard done by, having had to have crammed his extra-long body into a sofa for the night. Consequently he has a fight with Hermione, and somehow ends up showing himself off in what his mother deems, "dirty" underwear. 

Ron and Harry's case at work means they have to pay an unexpected person from a school a visit.

Ron needs Harry to help him purchase glasses for the wedding. Not seeing glasses, like... glasses glasses. That you drink out of? 

Harry arrives at an awkward time for Ron and Hermione, and he cannot help but get a bit giggly when his friends aren't efficient and hiding the evidence of their frolicsome deeds. It's not that he's NOSEy or anything. 

A happy friendship type moment is shared.

Harry and Ron are having problems putting what they want to say into words. Wiggins has an accident at work, and Ginny is feeling so ill she can't even speak properly. Luna is pleased she finally has friends to judge her "lover".
