I gave the woman across the street a bag of heroin.
Why would you give the woman across the street a bag of heroin?
I thought she'd spend time with me if I gave her the drugs as a gift.
Using heroin or any other drug as a gift is immoral. Drugs are illegal and not appropriate to give to others. Contributing to the drug habit of others is wrong.
Hey it got her to spend time with me. Why don't you agree with my way of fixing this? I'm so fucked up.
It sounds like you realize that you might have a drug problem. Why do you want to also contribute to your neighbor's problem? Maybe you and your neighbor could try to help each other avoid drugs instead.
