Terrified!!

Nico absolutely terrified me last night. I was working, and I always keep my cell phone on silent while I'm working. Most nights I don't even look at it until I get off work, but last night was slow. I snuck into the bathroom and had planned on sending a text to my darling husband. Instead I see two missed calls from Home, and two new voice mails. Right away this sets off alarms. We never use our home phone, Timmy always calls from his cell. The first voice mail is only six seconds long, and all I hear is a bit of whimpering. The second voicemail is 47 seconds long. The first five or so nothing, then I hear Nico, in a scared, pathetic voice say "Please, pick up!" and then for thirty seconds it's quiet whimpers. OMG!! I was freaking out. It's 11:30 pm, and those voice mails were left at 9:45 pm. I was so close to running out the door, but I stopped long enough to call Timmy's cell. If he hadn't answered, I was out of there. But, Timmy picks up with "Hey Baby, what's up!" I'm like, "You tell me, is everything ok?" and I explain about the voicemail. Then I hear him yell to Nico, "You told me you didn't call Mommy!" I was like, what the fuck happened? So here's the story. The boys went to their rooms at 9, like they always do for "bed time". Timmy, about 9:30 took the dog out for a walk, and then stopped at the tennis court so he could run and stretch his legs for a bit. The boys, came out of their rooms, and I guess thought Timmy had just up and left them. So they freaked out, and called me. I don't know why they didn't notice the dog wasn't in the house either? Why they didn't just look out their window and see his car was still there? Or why they went out the front door looking for him, when it was locked from the inside and we always use our back door anyways? And at-least they called me instead of 911, and at-least I know they know how to call me if they need to. But I tell you what, I don't ever, EVER, want to hear another voice mail like that again! EVER!! *****UPDATE***** So the boys just confessed to me that they knew Timmy had taken the dog out for a walk. But when he didn't come back right away, they feared he, and the dog, had been eaten by an alligator, and that's why they freaked out.
