Boys. If you like tennis, you can give him one. Tennis racket. Or give her a tennis ball that she likes and a sweatshirt like a star. There are many ways to like sports. You can send running shoes, pants and a set of sports equipment. Actually, it doesn't matter what you send. What boys care most about is whether the things sent by girls are careful enough. This is a key point. Of course, boys are careless. If you can make him careless and find your care, that is the best gift.
