Maelezo kwa mfasiri
I used the formal usted rather than the less formal tú. Instead of saying "when you don't know" I wrote "if you don't know" because it makes more sense in Spanish. "Dejamos" is literally "we allow/let" it could also be translated as "se deja", which would be impersonal, passive voice.
