Oh triggers can be quite ironic. I know some who trigger in church where one should feel most secure. Everyone will have different perspectives leading them to have different memories and triggers.
Spending time to work through things will keep our perspective as open as possible for even a room without a roof can be a good thing if you look at it right. For I can look at a place like Yosemite valley as a room without a roof and am happy and at peace because it has no roof to block the sun, moon, and stars.
