"if a friendship lasts for 7 years, it'll last forever"

No only a few friendships survive the course of time, you will lose many friends over the years

Not even marriages (they ought to go beyond friendship) are guaranteed to last after 7 years.

Nope. Me and my best friend met in second grade and he kinda f-ed me over.

False... incorrect ... bullshit

Nuh, was friends with someone for 11 years and he stole £120 worth of stuff from me!!...........................didn'taskforlifestory BUT ANYTHING THAT REMINDS ME PISSES ME OFF!!!

no

"Seven year itch"
...you can't even say that about marriage LOL

That’s absolutely no guarantee at all.

No, at least not in my case

I'd say 20 years instead, but meh

Nope

No

No

It didn’t for me. I didn’t even get a seat at the wedding even tho I was a bridesmaid

I've seen friendships dissolve after 30 year, and friendships turn to animosity after 60. So, no... no matter how long a friendship has lasted, I do not believe there is a guarantee for a forever-friendship.

No
