What is the best way to make friends in your 20s in MK?

Hi, I am 26 M and moving to MK end of April for a new job.

I enjoy having friends of both genders so keen to do mixed activities alongside the usual football. I love learning Spanish so any Spanish language exchange groups would be ideal.

I have a friend originally from MK who has moved put to London who says the social scene is completely dead so would appreciate any advice. I am coming from Amersham a small town off the M25 so I’m hoping it will be better than that social wise.

Anyway would really appreciate some advice as I am worried I will be isolated.
