<human>: Summarize the given text in a few sentences.

Me and my sister have generally been good siblings, not much conflict between us. But unfortunately we are not particularly close either. 

My primary concern is how she communicates with me sometimes. For example probably the most obvious example started when me and the rest of my family decided to get her a drawing tablet (she is into graphic design.) 

 I was excited to see her create some drawings with the new equipment, but whenever I asked if I could see any of the art I would be flat out rejected, "Can I see some cool are you made with the tablet Sister?" I said. "No, you may not see anything" She said. 

Eventually I learned that she never even removed the device from the box, understandably I was upset. Later I took the device out of the box myself and used it some etc. Fast forward to today,  now she finally wants to use it (nearly a year later) and I really want to help her get it installed on her computer. 

But she wants the CD that contains the drivers to use it (which had gone missing) so I explained that she can go to the manufacturer's website and download the drivers from there. Immediately I am fully rejected, "well you don't need the CD" I said. "I want the CD"

Sorry readers, but this behavior is hard for me to explain... hopefully another example might help. 

She was talking about what she was learning in her graphic design classes and mentioned something that was interesting to me, "what is BLANK mean? I said. "I refuse to explain that to you Brother" She said. 

Frankly this stuff bugs me, why would she refuse my help etc? Again I have trouble explaining it, but if anyone can help me that would be excellent!
<bot>: The best way I can explain it it road-block style, childish behavior for very specific things, generally when I want to help her or ask about certain things.
