Even though the school letter said that first years are not allowed their own broomsticks, Ruby was contemplating. Why couldn't she have one and keep it just to look at? It's not like she was going to do anything wrong. She couldn't decide; she knew for sure she wanted a broomstick servicing kit, though, for when she was able to have her own broom. And since she wanted to get involved in activities, she decided to buy "Quidditch Through the Ages" to read up on the wizarding sport. She headed to the counter with those 2 purchases, deciding she would decide about buying a broom later.
