May and Might

When I come back my room,I could cook eggs.I am so hungry,I could eat ten bowls of rice.I was so tired yesterday,and I could have slept for whole day.I couldn't go to the highest mountain,I don't have enough money. You haven't slept all night yesterday,you must be tired.It may be false,because I couldn't have  done these behaviors. If there will be one appropriate occasion next year,I may clarify myself about those misunderstand. Don't tell yourself that you can not get the champion,you might be running on the way. Buses are so exiguity this time,you might as well by bicycle.
