Why didn't Winston ask Mr Charrington?

[Sandy]

Winston tried his best to ask an 80 years old man how the life had been before the Revolution, but failed because the old man was simply too old.
Then he went to Mr Charrington's junk-shop, Mr Charrington was about 60 years old, who had a vague air of intellectuality.
I think Winston could have discussed it with Mr Charrington and hopefully got an answer there.
Thoughts?

Because it was too dangerous. The old Prole, he would never see again, so he was safe, but he bought things and then rented a room from Mr. Charrington. It would be too dangerous to keep coming back to the same place after asking him.

So far, I think Mr Charrington was very safe. ;)

Thanks Yefim! I've finished reading Part II, and you are right, Mr. Charrington was dangerous!

Also I found it in Part I Chapter VIII:
A twinge of fear went through him. It had been a sufficiently
rash act to buy the book in the beginning, and he
had sworn never to come near the place again.

So Winston didn't discuss this topic with Mr. Charrington.
