Here are the things I used to do when I was bored, before the internet existed, as far as I can recall:

- Phone a friend and chat

- Phone a friend and go for coffee, a walk, a drive, or just hang out at theirs or mine

- Phone a couple friends (one at a time) and arrange to (depending on time of day and schedule) go clubbing together, pubbing, to an event, etc

- Go alone for a walk (usually along the ocean), or into town, or to one of my 'third places' to hopefully run into friends

- Watch TV. This left one with a sad, unsatisfying feeling if a session went on too long: the TV studios geared their writing to the LCD. This is absolutely why MTV was so hugely popular before the net.

- Go shopping, or window-shopping (famously, to some people, 'the mall' was a 'third place'). Ideally, some non-chain store (eg: a specialty book store with foreign/obscure books and magazines)

- Play/practise a musical instrument

- Skateboard (something I have not done for aeons now)

- Rent, or rewatch, a VHS tape/DVD of a movie

- Read a book, a magazine, or a newspaper

- Start some mini-project (anything from laundry, to creative writing, to tending to a business card collection, to making a tee shirt)

- Write letters to friends who had moved away (long distance phone calls were expensive)

- Relax with a cup of tea, smoke cigarettes and listen to music. Often while doing this I would re-read my favorite books; easy to browse ones, like art books, old photos etc.

- Oh, and program my computer! Just... making programs without a whole lot of collaborative features, obviously.
