Not touching friends' bottom line is the most basic bottom line. No matter how generous and casual a person is, there is a bottom line that others can't touch. Once you touch his bottom line, he will definitely do things you can't imagine.
Give him some space. Although a friend is close to us, it doesn't mean that you can disturb his life anytime and anywhere. Don't mind your own business when your friends don't need your help. It may not help. Friends have the right to have their own private space, and untimely invasion will only make your relationship with friends drift away.
Respect is the most basic etiquette between people, and friends need mutual respect. Only when we respect others can we get the same respect from others.
Be tolerant of your friends and don't haggle over everything. Everyone's growing environment and life experience are different, and people's understanding of things will be different. If we all believe that our ideas are correct, it is easy to have conflicts with our friends and blame all the mistakes on them. Understanding and accepting friends with an objective attitude and a tolerant attitude can accurately maintain the boundaries between friends.
Although friends are close to us, they don't need any strict requirements, but they also need certain boundaries.
