Very normal to not have other friends from your school to join you. Especially for the faculty-only events.
There are MANY ways to meet new friends at McMaster. Go to MacConnector.. it is during welcome week (see the schedule) and is basically a big icebreaker game where you'll have fun doing activities with other first-year students.
Second, COME TO MACINSIDERS SOCIAL NIGHT! It's Sept 12th at Kelseys. We'll be meeting on campus and going down together (if you live on campus or don't know where Kelseys is). We do a lot of icebreakers and it is a smaller group (around 80-90 people) instead of hundreds of people like MacConnector. We'll have Karaoke there, lots of prizes, games, icebreakers, and will make sure you meet some new friends by the end of the night
Just come up to me at the beginning of the event and let me know who you are and I'll make sure of it!
Event details will be posted on our homepage soon.
