People use other people in life. It’s considered bad for one person to use another person in order to achieve their own goals however this happens all the time. To get further in life, people need to use each other and that’s just the way it is however that isn’t a bad thing at all.
Pretty much every form of interaction is using someone in some way; when two people converse they use each other probably to ease each other’s boredom and when looking at it, it’s completely acceptable. The two people may be using each other but at the same time they’re helping each other as well because more times than not, it’s better to talk to someone than talk to no one.
In most cases, using people doesn’t seem bad because it’s a mutual usage so all parties involved will receive what they want. With all of that being said, it doesn’t mean that I’m saying to use as many people as you can, instead I’m just stating some thoughts (but you probably know this).
If you use others and you’re only looking to benefit yourself then you’re a prick.
