Based on the information provided, I find that Oliver is similar to me because he also does sport on Sundays. While he doesn’t have any siblings like I do, I can relate to his interest in participating in sports during the weekend.
Liam, on the other hand, is somewhat similar as well since he has one brother like I do, but our weekend activities differ; he goes out with friends on Saturdays while I prefer to engage in sports.
Emma might not be very similar to me because even though she has one brother, her weekend activities don't align with mine as she watches films on Saturdays and isn't into sports.
Lastly, Phillipa has a sister, and while that's somewhat similar, her weekends consist of playing tennis on Saturdays and computer games on Sundays, which isn’t quite like how I spend my weekends.
In summary, Oliver is the closest match to my interests and weekend routine, followed by Liam because of our shared experience with having siblings.
