showing off is alot different than sharing things with others,I agree ,I dont like show offs,but I do like when others share simple tips and or knowledge.Its easy to see some clips on vids and believe what you just viewed is everything they have or do.When in reality its really a very small portion of what one does ,or has within himself.But all in all ,one can see in quick video minute if they are skilled or lacking,generally if one has done nothing except martial art for 30 plus yrs all day every day ,(not go to work then do martial art ) they tend to have skills,however Im open to suggestion etc....good chatting with you....thank you for responding
