Startled too easily?

A few years ago I was sitting here sketching the mantelpiece which like my mother in law’s was full of shells.pebbles,little stone cats etc.Suddenly a neighbour walked into the room and I screamed.I think my husband was in the hall so he saw him coming before he rang the bell.This man wanted to see me so My husband  told him to come in here without telling me.I must say both me and the man were shocked.So I think sometimes it might be good to be  less easily startled.
