Thankfully none of them have learned how to make phone calls or Pete would be ordering pizzas.
My Greys figured out how to use the tablet. Miss Merlin loves the crossword puzzle game. When you get a wrong word it makes a fart sound, which is one of her favorite sounds

So she will happily play with it for an hour, typing in words and imitating farts back to it. Obviously she can't read so she gets all the words wrong

. Actually she can barely see, but she can highlight a word on the puzzle, then type on the keyboard that pops up. She also likes to text people.
When I've been out of the living room for "too long", Oobie imitates the phone ringing. I yell back, "Hello! Who is it?". She answers, "Meeeee," and I reply, "I'll be over to visit soon.". Then she says, "Ok, bye.". And if soon doesn't come soon enough she imitates the text message sound.
Pete loves watching serial killers on TV. He laughs like a psycho when they attack people. Criminal Minds is his favorite show. He also has a crush on the female computer whizz actress.
