It never fails

Jamie's variation on Murphy's law:

If I am busy typing something important- the cat will climb on the keyboard and demand loving.
If immediately after coming in from the snowstorm waiting for the puppy to pee- the puppy will pee on the floor
After putting fresh sheets on the bed- you will spill something.
If the is an important lecture and an extra tutorial on the same day- there will be a nasty snowstorm preventing you from attending.
If you have finally regained mental stability after your girly time finished two day prior- it will return with a vengeance while wearing white underpants.
If your friend, you were worried about, calls- you will not be home.
If you planned on going sleep early- you will toss and turn all night
If you plan on a relaxing evening of watching movies and eating junk food- your best friend will have a serious dramatic breakdown
if you skip going with your friend to meet her friend-he is cute and single
If the sober girl joins in on drunken dancing in an empty bar- a cute boy will walk in.
If you get cashback at the grocery store, and really need it- the clerk will forget to give it to you.
If your nipples are tender due to girly time- you will catch your nipple rings on everything.
If my apartment is messy-people will end up visiting and seeing it.
