You were swinging under your kite due to not edging your board before take off. You were gliding across the water under the kite as you went to jump.

Edge against the kite as you take off. You will jump much higher and lessen the kite's tendency to get over your head.
Because you know it's a possible problem, make efforts to jump only when it's clear downwind.
You almost took me out once with your kite.

We all definitely started somewhere and none of us are perfect. Mistakes happen. But, knowing this, try to avoid doing things that you aren't great at right in front of other people. I am not mad at all, just giving sort of obvious advice.
