1. My friend created a roleplay survival realm and invited some friends
2. Someone on the realm got a nether portal
3. I got a nether portal
4: I went into the nether
5: I came out of the nether using the same portal I used to get into the nether
6: Instead of ending up at my portal, I ended up at the other person's portal.
This isn't a huge problem since we're only a few hundred blocks away from each other, but it is annoying.
We also had another survival realm earlier in the spring of this year, and the same thing happened to my friend-I created a nether portal first, he created one next, then whenever he went into the portal he came out of my portal.
