We all make life transitions that can separate us from the people around us. Circumstances weigh heavily here. If you see your friends primarily in one place and you decide it is best not to be hanging out in that place such as a bar, you may lose acquaintances or drinking buds. A friendship is a lot like a marriage and other major aspects of our lives, it is a decision. It is usually a good, pleasant decision to make but one born of mutual interest and respect for the other person.
The above was my way of saying, look closely and make a friend or two for life. It is well worth it to have someone to know you warts and all and vice versa. Friends in real life is also what I mean, we all put our best foot forward on the internet and it is a somewhat distorted image of who we actually are.
Proverbs 27:17
17 As iron sharpens iron,
so one man sharpens another.
A good friend will tell you when you are headed the wrong way and that is something that we all need from time to time.
