If you’re living by yourself for the first time then its helpful to share with another person. Even though you might not interact a lot but its always good from a safety, and social pov. However another issue is that person needs to match your mindset somewhat. There are people who keep records of 1 rupee payment, get annoyed if you have friends over. Not judging them bcos everyone has their own budget and privacy. However when choosing your flatmate - openly discuss all requirements related to finances, visitors, if they’re comfortable with bf/gf over, veg-non veg, timings, help around the house and hygiene (Ive seen people refusing to empty the kitchen bin for days bcos the maid wasn’t there). In the end considering all these factors, people prefer to live by themselves 😂
