Pubs, discos, etc of the 80s. Things were so fun, friendly and "innocent" back then. There were pubs everywhere, lots of people in them, so chances were that you could randomly go into one and easily find people you knew from school, or neighbours, or work colleagues, etc. No stress about not going in on your own, you'd soon find someone/several people to chat to even if you did. Regular discos in the function rooms of pubs every Friday or Saturday nights somewhere local, again, always someone there you'd know and just innocently dance the night away. A quick snog (or two) during the slow dances if you were lucky, then a bag of chips on the way home. You didn't need to go to the "clubs", especially if you were younger and didn't want the "harder" club scene, i.e. drugs, sex, etc. It was all so much more easy and innocent.
Nowadays, pubs seem to be polarised, they're either "old man locals" that are virtually dead, or they've turned into family restaurants with little or no "drinking" areas and in either scenario, virtually no chance of randomly bumping into friends etc to chat to. You'd really not go into either type on your own. They don't have discos unless they're special booked functions that aren't open to all. If you want a "dance", you have to go to the clubs, which are usually nowadays pretty horrible places with shady people, drugs everywhere, lots of overt sex, etc - again, not the places you'd go into on your own. And of course, very little chance of either being within walking distance of home, so you have the added cost and inconvenience of buses/taxis etc (if you can get one!).
I really long for the 80s style of easy, free and innocent pubs. I really loved the freedom of just randomly going out for a drink at night to one of our several locals and knowing I'd find friends there, etc., without the stress/faff of making prior arrangements etc., and if there wasn't anywhere, you'd just walk down the road to the next one. You'd make so many new friends, being "friends of friends" etc and quickly have large numbers of people you knew and could chat to.
I feel really sad that today's youngsters don't have that same experience and not surprised at all that so many have MH problems, insular, introverted, etc., as socialising is something you can practice and the more you do it, the more people you know, the easier it is and the more "friends" you make.
