Who's being immature now? Almost every single person that mention your judgment of cliff height was off also mention that they were stoked on the vid, and the guy charging and stomping.
Stop selectively reading, you're just being called out on having a distorted estimation of height. (by about 30% or more)
Everyone is stoked about him, but when YOU exaggerate height YOU get called out. Has nothing to do with people "hating" on your buddy. If you could read at all, every comment has a positive vibe to it save those relating to your overestimation of height, which is only fair.
