The summer has begun

It's officially been summer for a week now, and it seems like Mother Nature agrees with that. Walking around outside in the sun in the weather we've had the last couple of days is definitely not good for my mood, as it induces headaches and tiredness. Our bedroom is at the east of the house, and hence is bathed in sunlight all afternoon and evening. We go to sleep in an icky warm room (don't want to lie down on a prewarmed bed) and get up when everything is cooled down (don't want to get out when your bed is nice and warm)...
