I don't like it when people are trying too hard. That goes for clothes, for acting, for everything. It's just not good when it seems like you're making too much of an effort.
People ask me if there are going to be stories of Harry Potter as an adult. Frankly, if I wanted to, I could keep writing stories until Harry is a senior citizen, but I don't know how many people would actually want to read about a 65 year old Harry still at Hogwarts playing bingo with Ron and Hermione.
