  there's no need to be offended. sometimes those with the input you need aren't around to give you an immediate response. yt can't be a full time addiction... err... job... all the time. and sometimes posts get buried. if you're not getting responses, it's a good idea to do a friendly bump to put the thread on top for attention again.  
there's so many reasons why your yorkie may have pee'd on your lap. it can be marking. it can be submissive urination (which doesn't require another pet to be present. just a different reaction to different people. my yorkie will bark at some of my friends but not at others. i still can't figure out why. go figure.) it can be a urinary tract infection. or maybe he was spooked by something you didn't sense but he did.  
has he done it again? is his behavior changed in anyway? has he been neutered. if he hasn't done again since, then i wouldn't worry about it. if it happens again, maybe it's a good idea to take him to the vet and eliminate an infection as a possible cause.
