Here are some examples:
* Wir sind glücklich. (We are happy.)
* Die Kinder sind im Garten. (The children are in the garden.)
* Sie sind meine Freunde. (They are my friends.)
It's important to note that "sind" is only used for the second-person plural (ihr) and third-person plural (sie) forms of "sein". For other forms like "ich" (I) or "du" (you), you would use different forms of "sein".
