Availability reality

So.. She'll only work me 7-11:30 let's be real. And probably 4-9 anyway. And in Friday about 6 hours. Saturday and Sunday are in the air. That's :

4+4+4+4+6 = 18

Now I will work at least 5 days so let's add another opening shift on a weekend? 22 hours. 

Shit.

Now before I get pessimistic.. I just need to wait until things smooth out and a pattern emerges. I can't freak out at the beginning.
