Regret, anger frustration? How about sadness, sorrow, sympathy, understanding, even yearning!
It can be quite confusing at times. The compassionate feeling of pity I get if I see a pair of 'pioneer sisters' at midday is quite different from my reaction at seeing little kids in their suits and smart dresses being dragged from door to door on Saturday mornings when they should be watching Spongebob or getting up to mischief with other kids their own age.
After such a long time as a JW I recognise feelings of identification with them but these are immediately conflicted by a sense of rejection. Oh the life of an ex-cult member!
What about you?
