Life Sucks!

So the right rear tire on my minivan went flat over the weekend. It sat in my garage until hubby put on the spare on Sunday (The 5 of us cramed into his Ford Contour the whole weekend). Then today I went in to get it fixed. I went in hoping that there was just a nail or something in it and it could be plugged and patched. $20 and I'm outta there. No such luck. They told me the tire was unsafe to fix and that I would have to buy a new tire. Then my grandma, who came with me, told the guy he should check the other tires too, "just to be safe". To which of course I replied, "I don't have money to replace all my tires, grandma, are you gonna pay for them?" Well, turns out, both of my front tires were unsafe as well and also needed replaced. Great! As if we weren't already wondering how we were going to pay our car payments and buy Christmas presents, I had to shell out $237 on new tires! And that was at the Discount Tire Co. Why do these things always happen to me? Why always at times when I need any extra money I can find? Life is just throwing me many lemons and I don't have the recipe for lemonade!
