How to make my sister happy?

Let me explain first, I just looked at your profile and it looks like you are a girl. (Don't be offended by the word "seemingly", because this is the Internet after all, and different genders determine how I answer. Please understand!) 1. To coax and amuse. I believe that every girl likes to be coaxed and told jokes. Naturally, there will be less scruples among people of the same sex. Don't be too sudden at the beginning. It is best to slowly move around from a small matter to the top. Example (negative) Hey, hello! I have a joke for you! Isn't this a bit baffling? A little strange? I won’t give any positive examples, I believe everyone can do it. The jokes should be concise and not too old, let alone something that everyone has heard. You should also pay attention to her personality and clearly distinguish whether it is suitable for a cold joke or something else. Of course, teasing does not increase closeness, but only promotes it. 2. Help, a very simple method. If she has a problem, offer to help her. The process should be as detailed as possible. The time develops towards an action movie, a matter of seconds, but the process develops towards a soap opera as much as possible. It is delicate and has a long history (I really can’t find the word). ...), the effect is not obvious after 1 or 2 times, but the more it is, the better. 3. Chatting, this is not part of the amusing series, but the introduction method is similar, what to talk about, it is best to gossip... (Because around me Girls like to listen...) Yes,, or some topics that interest her, because this kind of thing can trigger a lot of topics, let's talk, if you can't stop, you have achieved the effect 4....It's hard to say later. I play some games with her. She can tell her what to play. She doesn’t need to have any airs or anything like that. Just be easy-going, peaceful, and friendly.
