The Internet wasn't just in everyone's pocket all the time. Frequently, using a computer network was an activity that you did with other people in the same room, e.g. in the Computer Lab (computers were expensive and complicated and not every room in a school or office would have the necessary power or communications wiring, so all the computers were kept in one special room) or an Internet Cafe (not everyone had Internet-capable wiring at home, so you might go to a business that offered Internet-connected computers as a service just to check your email) or a LAN Party (people used to physically haul their beige boxes, CRT monitors and network devices to a place to meet, connect and play games together - frequently just someone's garage). You went to a specific place to use the Internet, typically with other people around, and then when you left the place you left the Internet also, it didn't just follow you around everywhere all the time.
