This whole thread is cracking me up....My wife and I have been married for nearly five years now and she still doesn't get exactly what I"m doing...or at least, doesn't want to...
She basically makes up all these code names for what I"m doing. When I was playing the Vampire CCG, it was "making vampire noises"(????)....now, with Layonara, she's a "PC Widow"...but as she likes to say, "at least I know where you are, and you're not out drinking, using drugs and making passes at other women." Who am I to argue with that?
I will say, the one thing we had to discuss was the length of time I play at any one sitting. She was used to doing things with her friends tha took a set amount of time (out to dinner, see a movie, etc.). Because sometimes it can take a while to find people, get a quest going, etc. she was at first a bit upset of the number of hours I would stay on at any one time. I do think it's important, for those whose significant others aren't into Layo (and I am so jealous of those who have partners who play Layo too), to explain why it takes so long and that staying on the computer so long is not an indication of not wanting to spend time with him/her.
Good luck. And ditto on the honeymoon advice above...
