YIKES!!!!! I've needed oil for a while now! (seriously!) 
I'll have to take care of that before I head home for the 
weekend!!

But as for your question - yuppers!!  I find myself saying -
"I don't really need a new skirt" (I do), or "hmmm maybe my
kitten can wait to get her shots" (she can't).  I *try* to 
be reasonable, but I definitely have to try harder!!
