I've made a horrible mistake

So here's what happens to me when I'm on holidays. I lose all track of responsibilities and dates and times and everything because I am overwhelmed with all the glorious possibilities of things to do, places to see, people to visit. So this weekend I booked my flight home trying to maximize my time home by bookending it with the last day of summer school here and the first day back at school, which allowed only for just under two weeks. Disappointingly short, but still a decent visit.

Except I forgot that's when Folk Fest is on and when my ma is coming to visit. Which doesn't make any sense. So I had to cancel my ticket. Which costs $40. Plus whatever my new ticket, if I can purchase one, costs. GAH GAH GAH. Why did I think it was a bright idea to buy tickets when away from my calendar and pursuaded by cheap deals...... WHY?!?!?!?

I will make it home, I'm just not sure when now. Believe me, it brings tears to my eyes.
