Find free events
You'd be surprised by how many free events there are going on around you. All you need to do is have a little forage.
Comedy, music, theatre, poetry, art - you name it, we bet you can find it for free somewhere near you.
There's always a new band desperate to fill up their venue or an artist wanting to show their works.
You can even find free dancing lessons if you look hard enough. Maybe avoid that if you've got two left feet though.
And if it turns out that your free event is free because it's not very good at all, at least it's something to laugh about. Who knows, maybe one day you'll be telling the grandkids about it...
