Why not take a look at the socials page on this site. There are a number of things arranged by others on the SE1 forum such as book clubs, quiz nights and dinner clubs which you may like to join in or others looking for gym buddies,cycling companions and footie etc. Or you can try organise something yourself when it would probably pay to organise things a few days or a week in advance rather than try set up meeting for drinks tonight for example, as it takes a bit of time for people to see the posts and respond. Good luck I am sure you will soon be making new friends as there are plenty of friendly people in SE1.
Fifty four!??? that's nearly twenty years ago for me!
But nova,that shouldnt stop you joining our Social Events, we come in all ages, professions, backgrounds,but are united in being Se1-ers. By the way, nearly everyone is younger than me...possibly everyone without the nearly. So you'll find lots of people to hang out with I assure you.
