I moved it for you
Well, ok a couple of thoughts here.
1. I tend to agree with herbal. I think it is just the communication style now. My YS/DIL spend much of their time on technology and they LIKE me. My best friends daughter absolutely adores me (she's 11, what does she know...) but yet her nose is still in her Iphone for 75% of the time. So the other day, I was aggravating her and said, "Hey! You have Instagram?" I knew she did because it's the one thing her Mother has allowed her, no Facebook or Twitter yet at her age. Plus I knew her Mother's rule was in order to have it, Mom had to be her friend on it and monitor it. So I knew I wouldn't be worrying her about asking. She grinned and said, "Yes. That's what I'm doing right now. Why? You have it?" I told her I did and we sent each other requests then proceeded to take stupid face pictures and post them. She was cracking up. So, I had to enter her world to get her attention.
2. Yes, I used to love going to see my GM too, but we didn't have video games, iphones, ipads, etc. so although I loved her, I remember being excited because I knew we would do "something". It was baking, it was breaking beans while singing silly songs, etc. But in my world at the time, it was "something" to do. Yet, when we visited my other GM who lived a good distance away, I had to just sit there. I didn't dislike her at all, I was just bored. So have you thought about instead of sitting around the house or just going to dinner, trying to go somewhere they would find fun? Like the Aquarium, movies, amusement park, a kids arcade, etc.? Something you have near you that you could go to? I think kids do have so much technology and stuff now-a-days that sitting at any adults house doing nothing would be boring to them.
