Annsixty's has been so shitty lately (far from just "a bit of a bad day") with no prospect of improvement in her husband's or her health, or the many constant grinding days she is spending looking after him) that I am not at all surprised that she finds "frivolous and insignificant posts" such a waste of time and a source of yet more depression.
