hmmm... small problem

hi guys!!! i keep finding individual ants in my room in random places, but there's no line or anything. e_e i've been careful not to leave food, so i think it's cause it's so cold out lately that they're seeking shelter in my house. e__e sometimes i find them on my hands or on my computer as i type, but i can't kill them with a clean conscience so i've started picking them up with a light pinch that doesn't hurt them and throwing them down the stairs... when i have no choice cause there's a large group i call someone else to kill it for me cause it makes me feel terrible just thinking about it, and in the end i'm still their executioner.... i imagine an eighth circle of hell for people who kill ants who have to face the souls of every ant they ever killed. ok that's all goodnight everyone!!!! ^_^
