My mum is the person i have seen almost everyday of my life, and she's the person i've seen most of throughout my life (my dad goes to work at 8am, and comes back at 7/8pm but he goes abroad for work a lot, so i see her the most out of anyone) and i still couldn't talk to her about it, both my parents came into my room one morning saying it smelt like smoke, then grilling me about toking, so i said i swear on my life i didn't (even though they've found my pipe and could smell it, bad move, but i was kinda high, so don't blame me)
The first time, my dad was angry and my mum was trying to find out why i do it, then next time, my mum was angry saying "why are you doing this, now STOP!" and my dad was trying to ask my calmly why i was doing it (good cop, bad cop).
They've settled down about it now, and i know my room smells of weed, but they don't say anything, or search my room (to my knowledge) anymore.
