Possible New Job

So i have the possibility of a new job prospect which while it is not my dream job by any stretch would be a step up from what i am doing now. The really bad part though is that i am totally screwing over my current work if i start when my new job will possibly start. I hate to say it but i really basically run that place and they could not replace me in the next two years! I mean weeks, but prolly even in 2 years they could not replace me. I originally thought the new job was gonna be 330 til midnight so i could work my old job some mornings but now that is not the case and it is 10-630 which leaves me no time for my old job really. So i don't have the new job for sure yet but I think i probably will get it. We'll see. the ohter bad thing is we have a trip planned to @libertad's mom in florida in july and they have a no days off for 3 months policy so I have to talk to them about that b/c like I already have my ticket and dave has his vaca then and stuff and it would be almost at the end fo the 3 month period. So we'll see, wish me luck.
