Positive stress, yes, that's what I'm trying to think. Just trying to laugh/smile at any setbacks, troubles, stresses. We'll get moved. We're so blessed that it's all working out and nothing is going to dampen that (please remind me that I said that if/when I complain about it during the next two months!)
Glad your dad is doing OK; sorry about your unexpected bills. Did you completely pay off one bill (like a big dr. bill)? If so, there's your problem.
For several years, in our family, whenever we paid off a dr bill, something else costing big $$ came up. When our daughter broke her arm I put off paying off the complete amount for months, just paying part each months, because I was afraid something else would come up. I hope your big bills are done for awhile!
