I've had AT LEAST 4 migraines in the past 10 days

However, when I was picnicking here:



And saying hello to these guys:



And riding through these streets:



And walking across this river:



And getting lost and caught in the rain here:



And reading in the cafe:



And skipping down narrow streets:



And wearing a sweater and scarf in the middle of August:



And drinking wine out of mugs in the park surrounded by patriotic British people, with live classical music playing in the background:



And reading on the train:




I never ONCE had a regular headache, yet alone a migraine. What gives???
