Well since neither of mine have given me red or green robes yet I am thinking of trying to bribe them..........
I got my Red Robes and Green Robes while reloading auto-saves after being "surprised" by either daughter with crappy-coated crap with creamy crappy filling "gifts" like
pieces of plants (oh NIGHTSHADE?! LUCIA, how on EARTH did you know THAT WAS JUST WHAT I wanted? Just *a* single portion of Nightshade...wow, talk about intuition. I mean, I only have 300-500 upstairs! You know what? You should be a detective when you grow up!), potions that you'd use around level 10 (maybe...), a Staff of a Courage, Staff of Calm, some lame circlets, the most useless kinds of soul gems, and Silver Ore (actually, that was one of the better ones....). They are NOT expensive at all. Just rare, novel, and dare I say it, nifty.
Now that gold diamond necklace I got from Lucia or Runa after a 1,000 allowance?
THAT was a kid who appreciated moi...
another thing to keep in mind is that if you just give 1,000 allowances from the beginning, or even twice in a row, they stop making a big deal out of it. It gets the same reaction as a nice dagger ("YOU'RE THE BEST! THANKS!") I say give them 100 or 500, and every fourth or fifth time give them 1,000 and watch them go bonkers.
another tip?
No spouses. I have all homesteads and thane-related homes, and Ysolda (just like everyone else I've tried, especially Muiri...oh god, don't get me started...) just turns into a mental defective with Hearthfire. Sometimes I just violently sprint at her to get a semi-human reaction. If I have one more play thru left in me (at least before Dragonborn...), my tough but hot (yep--I actually succeeded in making not just an attractive female character on a game, but
a very attractive character! Even the scars on one of her cheekbones, which looks like she got it in a fight with that Rancor thing from ROTJ, is sixy!) Nord character is playing the field this time.
