he is sooooo lazy and always commands my mom and me to always to things for him...for example, cook for him,clean for him, and fetching. he always is just too lazy to get on his two shoes and just fetch things himself ts pmo. and the slightest mistake can cost me my lifeeee sdiebvefvbhebvhbrbvhfcjvcdnncejrf
