Me an my girlfriend, got together with her 3 month ago, went to her mom & little sister (7 yo) over christmas, wich I hadn't met before.
We're both studying videogame design together, and bought each other nerfguns and some other small things for christmas, so Christmas Eve quickly turned into a massive shoot-out between my gf, her sister, her Mom and me! xD
Her sister also Really enjoyed waking us up in the morning in the most lovely cruel ways imaginable, like hitting us in the face with plushy toys, dirty socks and so on.
After all the holidays were loads of fun tho, and we really enjoyed every last bit of beeing together with family, building with aquabeads that her little sister got...
...not playing, or working on, games for a few days and of course beeing engaged in those awesome christmas-sie family nerf gun shootouts. =)
