When we had no children I would sit through the whole lot & then 'take care of my responsibilities'
When we had 1 & then 2 children 'taking care of my responsibilities' bacame extreemly tiring. No-one wanted to help me out.
Eventually, the work load took it's toll (among other matters) & I just walked out of the hall, never to return again.
PS - we had some awful speakers. At times, even when just my wfe & I, we wanted to scream. You just wanted a beer, a bowl of crisps & the TV.
