Not interested in having any dinner - not interested in having a beer - I'm just crashing

Big day at work. Now I'm home I'm just crashing out in the chair. i'm not interested in eating a meal, or even having a beer, or or chatting to anyone (potential date or my kids), or having a shower. I live on my own so nobody else gives a fuck. it's winter so very cold (for Oz). just going to bed and fuck the world off for however long I can sleep for.
