I usually have had just a group of best friends but due to the pandemic, that's really changed a lot of things and I really only talk to a few people.
What about you guys? Do you have a single best friend or do you have best friends like as a group?
In my opinion, I have learned throughout life that it is quality over quantity. As you get older, you will realize that sometimes, relying on just maybe a handful of friends (5 or below) is the best thing to do especially considering that most people in life can be very sneaky, jealous, nosey, and/or backstabbing. A close bond of trust between both parties you have with said friend(s) is the most important thing. Sometimes in life, you need to cut out what longer suits you in order to make room for those who are even better or better things in general. You can know many people and have affiliations with them, but for me, very, very few are considered to be my "closest friends"
A lot of the times, people are only after certain things in life. Some are your "friends" only when they see benefit and gain. Some can be nothing more than drama waiting to happen. Now mind you, not everybody is like this, but be aware that they can very much indeed exist. Use your heart when trying to tell who are genuin beings and who are not. I use my intuition on this in most cases as your gut will usually tell you "hey, this feels right" or "no, I don't like this, this feels wrong". My closest friends are just 4. Family can also count as well. You will see as life goes on what contributions people bring to your table and what others do not and how you also shape them. It is a give and take relationship between both sides in order to be healthy. Just giving is never good and just taking isn't as well.
In the end though, you decide who you want in your life ultimately. Making choices that benefit your mental, physical, and emotional health are always first priority I feel but others may not. Just choose those whom you feel fit your life and make you feel positive, not constantly negative. Nobody is perfect but again, do what makes you happy as life is far to short.
