Sometimes you just have to give way when someone is sitting in your way when your surfing. Just pull off before its too late its not that hard..You've already surfed for 25 m so you had your fun.
The other night a young guy dropped in on me, i didn't actually see him until i ran into him in a close out. His board hit me and he was so upset, but as the mature adult i am i laughed it off, made sure he was okay and continued to encourage him some more for the rest of our surf. We were surfing with about 40 plus body boarders and it was super crazy.. Id be devastated if i had hurt him, even though it was his fault

Yes the back of my head is nasty bruised..
Don't like kooks in the line then help them, cant do that then get out of the water. Who is to say the line up belongs to short boards, long board or SUPS so next time you suggest it be a short board only spot, consider how you'd feel if it gets rezoned a soft board area only
I really cant see in the current conditions any issue with beginners being in the water sorry.
Edit i should say his board hit me because as i saw him i dived forward to block my board from hitting him. As an adult thats what you do..Don't just run him down..
