I sometimes spend way too long on BH & FB at night time after putting DD to bed and lose track of time and since I normally call DF to say good night and if its too late he lectures me on being tired and blah blah so sometimes, I'll call him at like 11:30/midnight, sound really sleepy and say
"Oh hey baby, I fell asleep on the lounge watching my shows a few hours ago......." hehehehe
I also buy junk food and stash the rubbish.
I pick my nose
I pee in the shower
I go weeks without washing sheets
