In German we only have the word "auch" and I wonder that there are two words in English for this: "too" and "also".
Here are some examples:
Peter got a brown hat. He also has blue shoes.
Peter is a nice guy. I am also a nice guy.
"Also" is exchangeable with "too":
Peter got a brown hat. He has blue shoes too.
Peter is a nice guy. I am a nice guy too.
Is there any example where "also" is not replaceable by "too"? (Or vice-versa)
Or do these two word have the exact same meaning?
