at my friend's

Michael was relaxed from the very first day at my friend's house.  His adaptability pleased me because we have to move worldwide every two or three years. But after he grew up, his caracter changed.  When someone rings the doorbell, he disappears immediately. He hides behind the dryer or the sofa until our guests leave.They want to see my cats ,but no way. One of the reasons I began to write blogs is to show my cats to the guests who were disappointed .
