@katoregama Thank you for this challenge, I really like it and have just started it. I understand our Sim never physically meets anyone during the challenge, but how about online chatting/postcards/online gaming? I've made it "easier" for myself as my Sim is insane and talks to herself *giggle* but I would think online gaming (using City Living) should be OK... as its not actually pursuing a relationship per se?
Also, it's going to be interesting to see how fun this can be with Pets - it's not quite the same to live by yourself with your pet, I wonder if the challenge still applies (at least for a relatively lazy cat, I think dogs should have more space)?
