So according to you guys, what Im doing isn't correct? Ok, I agree that I should give them space, but what's really bothering which really makes me wonder is that, why did they tell me that they didn't even know about these photos, since beside we three, no one else uses this computer, so what was the need for them to lie to me?This makes me think that perhaps there may be many other things too which they would be hiding from me, and keeping as secret.
Rose, out of fear maybe? when you keep threatening them that you will stop their internet access , they wont be telling you the truth..
I suggest when a situation like this happens , sit them down and reiterate the importance of due care , try to talk to them on friendly terms rather then acting the all powerful ...
and then at least you can be assured that they wont lie to you if you question them in the future ... you always want to touch the painted wall when you see "dont touch " written very clearly !
just be patient with them , keep explaining to them the security matters again and again occasionally but unless its something very wild dont stop them ...
