Here are some examples of how "tu se" is used:
* Tu se bahut achcha insaan hai. (You are a very good person.)
* Tu se kya kar raha hai? (What are you doing?)
* Tu se mujhe bahut pasand hai. (I like you very much.)
It's important to remember that "tu se" is informal. If you are speaking to someone you don't know well, you should use the more formal "aap" instead of "tu."
