Is my sentence structure ok?
Hi, I just want to see if my sentence structure is ok and my grammar too.
Hallo und Guten Abend! Ich heiße Rari und Ich mag es zu lesen! Ich spreche Englisch, Finnisch, und Deutsch.
Danke! Du bist wunderbar!
Hmm perhaps so, it seems as if there's a great deal of debate over when and where to use du vs Sie. This reddit though seems to firmly indicate that du should be used on the internet or else you come across sounding overly formal:
'du' is informal, how people speak online is most commonly informal, however in public, or to someone you don't know (or is older than you) I would recommend using 'sie'. While on the topic of formality if you want to be overly polite say 'Dankeshön'. Also, just for your street-cred I would not say "du bist wunderbar" since most germans never say things like that and may think you are a little odd. You never really say good things about someone to that person, you may praise an action however for example "das hast du ja toll gemacht" which is "you did that well" just in a more slang way, or if you want to talk like german gang members on the street you say "Krass" with is like "super cool" but most adults will look down on you if you say it. sorry for the long paragraph, I hope this useful rather than annoying. (also sorry for my grammar english is my second language.) I think generally though that your paragraph was really well written!!!
Your sentence structure is just fine but you should be careful with those exclamation marks. We usually don't use them very often, so you should probably chance them to simple dots. Also, the second "Ich" must be spelled "ich", since this is not the beginning of a sentence. And in German you never have a comma bevor the word "und".
Also, to whom are you writing this text? Because it is very unusual to end a letter like you did...
I really hope you won't take offense by my corrections :)
