I have a friend I see all the time .. but I don't share everything with her. We chat everyday about our day to day things .. eg work has been busy today, I had to go into the city for a client meeting, I'm watching EE on TV tonight, type-of-thing, but I leave things out. I don't mention:
That I have a PT come to my house twice a week
That I go for very long walks every weekend, alone
If me and my partner are out for dinner/drinks
