Aside from work and personal hygiene, why are you implying hanging out is mutually exclusive with those activities? Inviting friends to go shopping or do errands with you is a common way of socializing, among others. Commuting is also an opportunity to socialize if you take public transport or carpool and a friend or co-worker catches the same one as you. Socializing is tangent to a lot of activities.
