The appeal of sport bypasses Eileen as the thought of getting sweaty, dirty and exhausted for fun (unless is with Derek) is not for her but she can see the usefulness of sport. It can unite people and it encourages human endeavour. Jenny is fond of tennis and swimming and swims regularly herself. Eileen could swim but doesn't. Like most fairies she takes the attitude why swim when you can fly though Jenny has pointed out that attitude is not going to bring home the gold medal for the 1500 metres. And flying in front of humans is likely to cause consternation rather than applause for an achievement.
Eileen opposes these on the grounds of cruelty to animals (as a fairy she too has ultra sensitive hearing and fireworks are much noisier than they used to be) but does recognize that organized displays can be very useful. She only wishes they were over a couple of nights only so distress to pets is limited. She has been tempted to "magic" this into being but the thought of being caught out by someone and made to explain herself stops her. Eileen won't explain herself for anyone.
Eileen is no good at this. Jenny is. Eileen thinks it's because she is so used to getting magic to take her to wherever she needs to be and besides there's no way she's taking instructions from an adenoidal female disembodied voice. Jenny thinks it's because she's taken the time to learn how to read a book of maps properly and sees Sat Nav as a useful guide but not something to totally rely on given it will send you up any dirt track if it considers it a road.
