I was fighting mentally with a stupid insect just now. My window blind was pulled but it still flew in. I think the black insect was too heavy, because it flew slowly and unsteadily. I stared at it for around 10 mins, until it flew away forever. Now the windows in my house are all shut. I am now chatting with my brother online. He said it was no use. The insect may fly out from the toilet bowl. Gruesome!!
