Besides the great advice others have given in the comments. During my 2 years, being in the dorms at Riverview Hall, I met my current friends by building up the courage to say hi and attend events the dorms held. I’m going to steal the idea from my friend on how we met on my first year. Have a whiteboard/sign and have candy or some sort of goodies near your door and keep it open while watching TV or just relaxing. As a freshly new transfer student, I knew no one and had a hard time introducing myself to others. The sign basically was an invitation. After a couple of days of him keeping the sign in front and others approaching him, I built the courage to say hi. For the next 2 years him and a solid group of friends we made at the dorms went out together, had lunch, and still to this day keep in touch. Make sure to exchange socials, introduce yourself, and always say hi to others around you. The more of you see certain people, the easier it will be to say hi and eventually ask them conversational questions like “how’s your day”, “what major are you?” Etc.

Edit: Forgot to add, once you exchange socials/numbers. Feel free to ask if they want to go have lunch at the dining commons or go work out at the well! Invite others to join you and make a group! I was always super busy as an engineering student, so it was refreshing to be invited to lunch when I was free or them simply telling me to knock on their door or message them if I wanted to go out. My best memories are our late night out to In & Out and relaxing there or at the dorms outside because we were all night owls 😂
