I got bedbugs!!!!!!!! Bedbugs, the most insidious bugs in the world!!! Before I came to New York, I never heard about this bug, Until last month..... One day, when I woke up, I felt my arms so itching At first I thought it was allergy, because I didn't find any bugs in my room and I just ate 20 lb cherries in that week. After day and day, it not only getting better, but also getting more. So I asked my landlord, my housemate, some people told me that's because my skin too dry, just put some lotion, but one of my housemates told me it definitely is bedbugs, and few years ago, a guy who lived here, he got bedbugs too. I've washed my sheet, clothes and cleaned everywhere of my room, but the bedbug still there. This week I tried to put some Eucalyptus essential oil on my skin, um..... a little bit better I think. Oh...... Does anyone can tell me the best way of killing bedbugs??? I'll appreciate it > <"

My first day of GreyHound Bus Trip in USA My bus trip was started today. The first stop is Augusta, Maine, it's capital of Maine state, but the interesting is it so small and empty. After I walked 2 hours, the view still same as before. Fortunately, I found a chinese restaurant, it call " Chinese King ", they have nice waitresses and boss, not to mention the food that is how taste good for me. The boss knew I'm along to travel America, he didn't accept my money, and told me where can let me stay all night for waiting my bus. How warm this world!! By the way, now it's 11:15pm, I still have 7 hours have to wait, OMG......
