Dunno what the hell is going on with mine tbh. But, whenever my grand parents come round they ignore me or show very little interest. This has just come on in the last month. I'll be like 'hi' and they'll sorta look at me and say nothing. I haven't asked my parents why they are acting so weird towards me yet, but I just feel that I an't find the courage to ask. It really pisses me off, I mean I've done nothing to upset them, I'm not a mean person. It's just totally unlike them to act like this towards me. Something is up...
I'm sorry to hear that, but you shouldn't assume that something is up. I remember a similar thing happened to me with an older aunt of mine. Turns out her hearing was getting bad, and she just didn't hear me talking to her.
I've had that experience of thinking people were dfeliberately ignoring me, and I was wrong. It was because I gave more weight to some single bit of evidence than was justified. That's the problem with reading Sherlock Holmes - in reality he'd often be wrong, because things happen for less likely reasons, including coincidences, much more often than you'd expect.
