waiting for opps

Earlier today when I was trying to grab opps from 3ps, I never grab any. Every time that show up it turned gray right away. I keep waiting and waiting for an hour but nothing. So I continue doing my chores here at home but every now and then I run to the computer and checked again. Until I finally grab one, it is okay at least I got one and I was happy. I like to stay longer on the computer waiting for the opps but I cannot. I have a lot of things to do here with my children
