It is a typical case. A young professional has just moved to a new city. She is very active in her new job but wishes to meet people socially outside of work. How does she do this?

  Signing up for a night class is always a good starting point. Not only is it an ideal way to meet like-minded people,it can also be a great new learning experience. Pubs and clubs can be a good meeting place but can be a bit hard if you are on your own.

  Join a gym

  GL-14 health club in Manchester city centre is a gym which also has lots of member activities outside the gym from charity fashion shows to dinner dances giving members a chance to socialize away from the treadmill(繁忙的工作). Or if you want a gym with a difference,try a“Green Gym”for people who want to exercise but wish to be outdoors and doing something that will benefit the environment at the same time. The“work out”could involve such activities as practical conservation or gardening work. It’s a great way to get people’s heart and muscle working. And many agree that meeting other people and having a matter and a laugh is a big attraction of the scheme.

  Reading groups

  In the Reading Groups,Jenny Hartley suggested that there may be as many as 50,000 people in reading groups in the UK. They range from informal groups of friends or colleagues who meet in someone’s home or at the local pub,to discuss a book. If you want something a bit more structured,lots of libraries have reading groups and could have a broader group of members.
