Going to someone's house to play will bring some inconvenience to them, so it is necessary to bring gifts to express your feelings. Since your bestie's family has everything, there is no need to buy some very expensive gifts. Just buy some simple gifts that can show your feelings. Here are some suggestions for you, I hope it can help you.
1. Give him a very crafted ornament, which is more practical. It can be placed in the living room at home. It is simple and can decorate the room. Crafts are still very popular for adults in their forties and fifties. For example, some inner-carved crystal ornaments, and those that can be inlaid with photos, are very popular in home decorations.
2. DIY chocolate is also a good choice for gifts. Do it yourself, and let your bestie's father feel your heart. Eating chocolate is also good for middle-aged people. It can dredge blood vessels and prevent diseases such as cerebral infarction. I believe that your bestie's father must be sweet after receiving your chocolate.
3. I suggest you go to some websites that allow you to customize gifts and order a unique little gift for your bestie's dad. For example, you can make a photo of your bestie's dad on a pillow. Your bestie's dad will definitely love it. I think this is also very warm. In short, no matter what it is, as long as your intentions are conveyed, it's fine.
