I came across this guy a few weeks ago.I like the way he explains things. I frequently revert back to watching his clips to whatever I am learning at the time as a refresher.
I especially liked the one from gringoespanol "How Words Work (Verbs Like Gustar)" because the penny finally dropped for me that some words have no translation and he explains it very well
I love his stories! They are easy to follow and learn new vocab from. Here is his story focusing on the preterite: https://www.youtube.com/watch?v=G55RSO0UviQ&list=PLA49C386B2886A54D
Thanks for enlightening us about him, his videos on preterit versus imperfect helped a lot.
