alt Hacker NewsI'm a native English speaker and taught myself Spanish. I focused heavily on grammar and verb conjugation such that I can explain verb tenses and their uses to someone else learning Spanish, yet I struggle to explain the same to an English learner. Either I didn't care enough to pay attention during my English courses or it's not taught.
To be fair, verb tenses in English are so easy compared to Spanish, it's not really the same required effort. As a native English speaker I found learning other languages a shock for how verbs change so dramatically according to context.
