It has to be said that at the moment the issue of 'planning ahead' is feeling rather raw. We're in October and it seems like no time since February when the frantic ticket booking for Richard II. Now that's patently 'planning ahead' on a somewhat ludicrous basis.
At the other extreme, a new policy (semi-predicted in advance but not 'formalised' or notified beyond direct circle) was decided on the Thursday 19th before implementation on the Monday 23rd (and which has since already been 'clarified' - aka changed - twice).
Now these are clearly extremes, but my instinct leans to the former for clarity over the latter. I would sooner know stupid time in advance than at the last minute. I'm not anti-spontaneity, but time and place and sensible predictions people are likely to smooth my responses.
So I do get rather irritable at the tendency of others (I hasten, not anyone I know online but rather IRL friends and contacts) who will persist in last-minute invitations. You know what, we usually have a good time if we can go at short notice, but by lordy it gives me the cranky to know you clearly knew about and/or had been planning for an event for weeks and only thought to invite us the day before.
I can get myself in the mood, gear myself up for social interaction, if I know about it in advance. I can manage my workload ahead of the event so I'm not trashed before going. But if I'm just landed on with an invitation my instinct is going to go into hyper-crank mode ranting about the lack of notice. There's transport to sort and crucially FOOD. And a cranky HUNGRY Lisa is not a socially pleasant Lisa to have around you.
I'm just saying.
