I have a friend (whose identity I won't reveal, since some of you reading this post may know this person) who has changed drastically, and not in a particularly good way. I considered this person one of the nicest people I knew; someone who was fun, kind, and considerate. Now, said individual seems to have withdrawn to a not-nice place. This person does not seem to have any time for certain friends, and does not deign to answer e-mails or return phone calls (a real pet peeve of mine). Invitations are declined (or ignored). There's also a hardness in this person's personality that wasn't there before.
I know that everyone changes as the accumulation of life events shapes us. But the changes usually aren't that quick and drastic. I'll admit that I'm confused about the whole situation, but I also realize that I can't let the actions of someone else (something I can't control) get me down. So I'll write this off as a lesson learned, with no resentment toward anyone. I think it's best to just go about my own life and let this person figure things out for themselves.
P.S. I know that I've done two serious posts in a row. I'll try to make the next one a bit lighter in tone.
