Aaah yeah, that's annoying as hell. Granted, I grew up in a family where during moments like that, you generally weren't "allowed" to have stuff like that out and about. Like if I went to the Christmas party, I wasn't really supposed to bring my Gameboy, music, etc.
It must be another generational thing. *Shrugs* I imagine it's like those kids that constantly text under the table when eating dinner with their parents.
