I think friends don't need to be the same. Different friends can bring us new experiences and help us grow.
My best friend Tom is very different from me. I like reading quietly, but he loves playing sports. Every weekend, he takes me to play basketball, which makes me stronger. When he has trouble with English, I help him with grammar and vocabulary. We learn from each other and have a lot of fun together.
In a word, different friends make life more colorful.
