Stupid People !

Just now when i went tuition , I went to the Minimart to buy some snacks for myself , so I thought , mmm , maybe i should buy for my brother and sister , when i reached home , i give it to my sister , she said thanks ! But you know what my brother said , he said why you buy this for what ?! Waste Money ! He didn't even thank me ! Then i say , if you don't want , then say you just don't want ! Why must say all those crap to me ? He USED to be kind like , erm on Monday , but Suddenly , the past few days , he so mean to me !!! :(
