Flat Tire

So this morning I was actually doing really well with time, I wasn't rushing at all. I ate my breakfast, walked the dogs, and even gave them a longer walk than normal. Got ob my bike and thought to myself how nice it was. Then not even 5 minutes out I feel a pop and start hearing a sharp hiss. So I turn around and get half way home when before there's not enough air in my rear tire to ride on. Then walk the rest of the way. After patching the flat (after seriously contemplating just working from home) and then riding my 6 miles, I am now on my bus and was only set back about 40 minutes.
