I found this in my little sisters school bag

Yes. I used to bite my nails my entire life without really realizing why would I want to stop. It was effective, it kept them short and clean, perfectly practical, and I didn't care that it looked bad until a few months ago. Then I just...stopped. I just didn't want my nails to look like crap anymore because I became self conscious about my hands that are already not very pretty, plus I started enjoying the feeling of tapping them on a hard surface, so I just kinda stopped biting them.
So, in short, yes, and I didn't find it as hard as I'd originally thought it'd be.

Yeah but stopping something that your body is chemically addicted to is harder than stopping something that you're psychologically need to do. I agree that both are hard but in this case I think cigarettes are harder to quit.

Well, yeah. My point is that compared to drugs, weight from good food is easier to put off than the addiction, which is why food is better. I never said it's easy to quit an addiction and I have no idea where you took that from.

I took that from you saying that whole thing about you biting your nails and how it was hard to stop and then you just did one day. But yeah I guess you were just saying that to share. But yeah i agree with you it's a lot easier to put off weight than the addiction. And people just do drugs insteaad of eating good food because it just makes you feel way better. I'm not saying that it's good or good for you but they're kinda hard to compare.

Yeah, I was saying that just to share. I guess it's just an entirely different feeling. I feel kind of lucky because I'm both sort of "addicted" (obviously it's nothing compared to actual addiction) to eating tasty food and to the adrenaline rush that comes with working out. They're both different feelings, and they're both awesome. Drugs are entirely different, but I don't care, I have no intention of ever trying them as they just don't give out any allure to me.

Yeah the rush from working out feels really great! And yeah in the long run the side effects from drugs really are not worth it.

Quitting a bad habit is easy and simple with the right motivation. I used to be borderline obese and a smoker. I first lost 70 lbs then quit smoking. I was afraid of quitting smoking because of the inevitable weight gain, but I only gained back around 25 lbs and as of today I've lost 15 lbs of that weight I put on. But the trick is all mental.

Maybe because guest wanted a kinder

well it is really weird for siblings to do that, what prompted going through their bag? The smoking was probably dealt with and we can't do anything about it anyway, but why was the sibling going through the others bag in the first place? it is weird and I'm half awake if even that much sorry.

it's not that I don't care about the cigarettes, I'm wondering why the sibling just started going through her bag. Why is that such a negative thing?

It's not.
Guest probably just wanted a kinder. I want kinder. I'm kinda ashamed to admit I took a bar or two from my siblings a few halloweens ago.

that makes sense, as long as they knew the kinder box was there

If you have a sibling, you always know where they're hiding their candy. I guess this person saw their sister hide the kinder box in her bag and went to sisterly steal some.
