In German, 'ich' (I) is capitalized only at the beginning of a sentence. Unlike in English, it is always written in lowercase in the middle of a sentence.
Ich komme aus Spanien.
I come from Spain.
'Ich' (I) is the subject form, or nominative, and performs the action of the verb. It either comes first in the sentence or directly after the conjugated verb when another element is in first position.
Ich lese ein Buch.
I am reading a book.
When the speaking person is the object of an action, you use the forms 'mich' (me, accusative) or 'mir' (me/to me, dative), not 'ich' (I).
Er hat mich gefragt.
He asked me.
we
'ich' and 'wir' both refer to the person speaking, but not in the same way. 'ich' means only the person who is speaking. 'wir' means a group that the person speaking belongs to. This can be a small group, for example friends or family, or a larger group such as a class or society. Learners confuse the words when they do not pay close attention to whether only one person is speaking or whether other people are included too. Remember: 'ich' is one person; 'wir' is me plus at least one other person.

Ich habe morgen einen Termin beim Arzt.
I have a doctor's appointment tomorrow.
Wir gehen nächste Woche zusammen zur Behörde.
We are going to the government office together next week.
