A "housemate" is a person who shares a living space, such as an apartment or house, with one or more individuals. Housemates typically split responsibilities like cleaning, cooking, and paying bills, which can help reduce living costs and foster a sense of community. Living with housemates can lead to friendships and social interactions, but it may also require compromise and communication to manage different lifestyles and habits. Clear agreements about shared responsibilities can help maintain a harmonious living environment for everyone involved.
