Parents will always know if their kids are doing drugs - its this innate ability they have to know
im pretty sure A LOT of parents, especially (or mostly, since theres a correlation) the parents who try to shelter their kids overly or who are particularly narky/harsh, will tend to ignore even blatant proof sometimes and continue to beleive that good little johnny or sally is infact good and doesnt do what that naughty greg or tracy does.
I've seen parents ignore obvious signs but mostly they fail to put together little clues. parents WANT to believe that their child is good and that they've done a good job.
Both my parents know. my mum is fine about it, they were both trippers in the 70's and she's fairly cosy with the concept. i knew she wouldnt mind and was fairly open about it, and she straight out asked me when she suspected. a little freaked out by my frequency maybe, and worried when i look too whacked out sundays, but trusts me and my judgement. She has a slight dislike for hallucinogens, mostly LSD, since she didnt like it.
my dad on the other hand is a reformed ex tripper. he's majorly agianst it, and doesnt believe i should get the chance to try anything, even though he got that chance (and took it eagerly with both hands from stories ive heard). He was one of those who ignored blatant signs until it was blindingly obvious (2 grams of whizz in my drawer).
He's learned the hard way, twice now.
I get lectures, and the ice is slippery for a while every time i'm wasted or caught with quantity, and the odd spiteful sly remark, but generally he lets it slide because he knows i'll go live with mum if he makes things too tense. or at least i think thats why. He thinks they're keeping me in the rut i'm in, however the rut started long before the drugs and is there even when i have breaks. he doesnt buy this though.
peece.
