Shoplifting- why do people steal?

They steal because they are chasing that first high, the feeling (rush), they got when they fisrt stole something from a shop. This behaviour is similar to the behaviour of people on drugs. They continue to take the drug because they are chasing/looking for that first high feeling they got when they took the drug for the first time.

As long as they continue stealing without capture or challenge, they'll keep on doing it because of the dangers and risks that give them a high. Until they are caught, they'll keep on stealing because of the thrill even though you hope they'll stop before they're caught but they need to be caught in order to stop and lose the thrill.

Gold digger- what is a gold digger?

A gold digger is someone that allows somebody else to pay for them all the time, leading them on. These people, stereotypically women, prey on the rich and ugly with low self esteem but big wallets. By using their victims low self esteem against them, they can get practically anything they want. These men , the victims, use the only thing they have, their money, to keep these insanely beautiful women interested. The men give the women everything they want in return for sex and commitment. Which is similar to prostitution, giving out sex in return for money. These women (gold diggers) are nothing but expensive upper-class prostitutes.

Stalking-When does observation become stalking then obsession.

I think its when they turn from obserserving someone to get an interest or start a conversation (noticing something about a certain person) to wanting and/or knowing everything about this person, from their likes and dislikes to their morning or evening rituals. This person doing the stalking must not be a relative or partner because most people know pretty much everything about their partner, and this is not stalking
