I've come to this same conclusion, but rarely express it because it's possible I'm just different. And I'd even go one step further, I think what a lot of people say friendship is, isn't actually what human friendship is in practice. I think these unrealistic expectations undermine real-world friendships because they always fall short.
Theoretical friendship:
- Completely perfect and devoid of all realities of life
- No jealousy, no competition, no negative feelings
- Timeless and immortal
- No effort involved
- Completely balanced and healthy for everybody at all times
- Able to talk about every topic
Realistic friendship:
- Temporary at first, may or may not build into something more
- Often starts with a simple exchange of banter on common interests
- Multiple opinions/topics that are mutually avoided
- One person often tries harder, one person often values the relationship more
- The relationship may or may not even be mutually healthy
- Many will hit a point where they become more effort than they're worth and end (e.g. moving)
- Some will never grow out of one or two common things to bitch about
