It sounds like you're going through a tough time with your dad, and I totally get how frustrating and hurtful it can be when there's distance and hostility in a relationship. Here's a more relaxed approach with some actionable steps and psychological insights:

1. Dig Deeper: Instead of just focusing on the surface behavior, try to understand what might be going on underneath. Maybe there's something bothering your dad that he's not expressing directly. It could be health issues, worries about aging, or even just feeling overwhelmed with life changes.

2. Get Curious, Not Furious: When your dad accuses you of being a "web hacker," it might not be about you at all. Sometimes people project their fears onto others. Maybe he's been reading scary stuff online about hackers, and now he's suspicious of anything related to technology. Asking him calmly about why he thinks that way might open up a conversation about his fears and concerns.

3. Speak His Language: If your dad is angry or distant, it might help to approach him in a way that resonates with him. Maybe he responds better to practical solutions rather than emotional talks. Or perhaps he values humor and light-heartedness. Finding common ground and adjusting your communication style can make a big difference.

4. Plant Seeds of Connection: Even if your dad is pushing you away, keep planting seeds of connection. Send him a funny meme or a nostalgic photo from your childhood. These little gestures can remind him of the bond you share and break through the walls he's put up.

5. Take Care of You: It's easy to get caught up in trying to fix the relationship, but don't forget to take care of yourself too. Set boundaries to protect your own mental and emotional well-being. Surround yourself with supportive people who lift you up.
