That's where I draw the line. Call your grandma! Call your mom too, while you're at it.

That's really wonderful that you still send your grandma cards. I guarantee you she saves every one.

Don't worry I call all of them too. I need to do it more often though, I've been slacking.

That's awesome, I've wanted to build something similar like a walkie talkie that's connected to a peer over the internet, you just press the button to talk instantly!
