for me, thought are really abstract and it takes a bit to translate them into words. and even though i’ve spoken english for around 8 years, i can still notice that i take way longer to write things in english than my first language. though i guess that might be related to me basically only listening and typing in english and not actually talking out loud enough. when i do talk out loud, i still have trouble translating thoughts into words. in my first language, portuguese, it’s the same situation, it just takes less time.
