As we go through life, we will meet a variety of people and will build complicated, personal relationships with them. There are various types of relationships such as friend, work, romantic, and family relationships. It is important to remember that relationships are as individual and different as the people who are a part of them. There are different expectations in every relationship. Sometimes, these expectations are made clear by talking about them, but other times they are just unspoken rules that develop as people spend time together. Friendships are platonic, meaning there is no sexual interest involved. These relationships fulfill our needs as humans to be around other people who we feel are similar to us and feel valued, secure, and appreciated for who we are.  Some relationships are casual "acquaintances," and include people you might pass in the halls and smile at or say, "Hello." Acquaintances help you feel connected to the outside world, but they're generally people you wouldn’t call up to hang out. The only expectation you have of your casual acquaintances is politeness. Other relationships are casual friends. You may have met by chance (for instance, because you are in the same class) and you may interact on a regular basis based on your shared interest or common schedule. You may chat with these people about surface-level topics, but you probably don't know much about them as individuals. More intimate friends are the people you trust and choose to be with when you have a choice. These are the people that you feel that you can be yourself around, and you don't have to worry about impressing them. Intimate friendships can require a lot of work to maintain, because you owe each other attention and time as part of your friendship. Best friends are those intimate friends who have proven to be faithful, loyal, and trustworthy; these are often relationships that have stood the test of time. Best friends feel as if they know each other inside out. Not everybody has or needs best friends, and that's...
