Yes - it's roulette - well put. I think my vacation expectations are so low now - if I do go - I know there will be days when I'll have to just sit it out...it's so frustrating and it's not how I want it to be- but it is how it is. Damn the brownie if that was it - who knows? That's the thing - there are times I do know what set it off - but that is about 10 percent of the time - the rest is - who knows? Rest up and hopefully you'll have a better day today or tomorrow on your vacation.
