I have decided it's time to buy the bullet and start having driving lessons agains. I recently got a new job which I can reach on public transport, but I am wary of bus routes changing/being unreliable and whatnot, and basically just want a backup plan.
But I started learning to drive years ago age 17, and failed my test. Repeatedly. To the point that it is now a massive deal and I hate hate hate talking about driving and driving tests. Mainly because people just cannot help giving advice and suggestions and telling me what I need to do 
In a moment of madness I booked my theory test and am looking at driving instructors, but I really don't want to tell anyone, including my lovely DP. I just want to do it without any fuss whatsoever.
Would I be massively unreasonable not to tell my DP? He would be nothing but supportive, but I just don't want to. Would you be really pissed off if you were him?
