Hi hellywelly- it isn't uncommon for people with major worries about issues relating to money, health, etc to:
(a) want to share their trials and tribulations with others and then 'dig in' and dismiss advice and
(b) try to escape from the bigger problems at times by taking refuge in familiar territory and to appear almost obsessive about seemingly trivial things. I think desktop is entitled to have some time away from her problems but I do wonder whether she benefits from our advice.
