Fail time.
Since my GF got pregnant I've been on a ban from smoking in the house. I would never do it now anyway, as I don't want my son breathing in smoke. So in my self-imposed smokers exodus, I took to putting my cigarette ends into empty beer cans, so as not to dirty my garden by just throwing them anywhere. Said beer can usually resides on my patio table.
Just went out for a cigarette, beer in hand. Put said beer down to answer a text. Grabbed beer nearest to me on completion without thinking, and now I'm the proud internal owner of at around 7 empty butts, and half a beer that's been out in the open air for around 2 weeks. It's at times like this I wish I still had a gag reflex.
FML.
