When you get up at 5am on a day you could have slept till 10am and decide to rearrange the living room on your own.

And then plan in detail how you are going to redecorate the living room and the rest of the house (with little money left in the bank from the last spending spree).

When everything being sold on eBay seems like a good idea to buy.

When you purchase an entire outfit or 5 from eBay that is in 4 sizes too small because you just know in 2 months you will shed the weight on the new diet you have come up with.

When you site down with your nurse and she asks to see everything you have bought in the last week and its covered the living room floor in small sizes including those 6 inch heeled pvc boots (that don't fit and you could not walk in them anyway) that you bought to look good on the school run.
