I set my alarm on Monday to 'if I wake up in time, I'll go to orienteering' after flying in at 10:15 the previous night. I only seem to have gotten tired today though and had an afternoon nap on the couch, with the full expectation of a phone call to wake me up (it always happens with afternoon naps yet I only receive about one call per week) but instead Tash came home early and woke me up by opening the front door.
Hypervigilant! When my ears were blocked I managed to not hear gutter overflowing rain and an alarm which was within arm's reach. Now I can hear the tv upstairs!
