Thank you! The hardest part was actually the first 100 days or so. After that, I managed to include it into my daily tasks. With a streak of 548, I'm sure you know how hard it is to keep it going;).
The other thing is that English is not my mother tongue (which is Portuguese). So, I study both English (from Portuguese) and German (from English). That improved my English skills a lot, but also made it much harder to learn German. I had to do this way because when I started, there was not yet the pair "German from Portuguese". When it was created, I was already used to practice both languages at once...
Very interesting. Thank you, English is not my mother tongue so I was confused by a Duo detail. The correct answers included one stating this: "I am back in a minute". Hence, I was thinking: if this sentence is correct, then it would be reasonable to say "I am back in a moment". On the other hand, this was something I never saw anyone saying before in English. Now I know why: it's not something someone would naturally say. And then I'm stuck in a bit tricky choice: either to deliberately practice unusual expressions (to enrich my skills) or to avoid them (to prevent learning wrong sentences). Anyway, thank you very much for your help! Appreciated!
I think of it like this: "I'll be right back" -- I will return in a short amount of time (minutes at most usually)
"I'll be back soon" -- I will return in a short-ish amount of time (from a few minutes, to a few months/years. "Soon" can depend greatly on context).
Is there the same subtlety in this phrase and another similar one? If so, what are they? Thank you!
'I shall be back in a minute' is also correct, indeed better English at least here in the UK, but is marked wrong: https://screenshots.firefox.com/ASEX6ChKsh5xBeRZ/www.duolingo.com
This is a case where "bin" is translated as "I will be" instead of "I am", "gleich" would be translated as "immediately", "wieder" as "again" and "da" as "here". So literally it would be: "I will be immediately again here" which in regular English will be: "I'll be right back".
