What does this mean.?!

[DangerousMouse]

So, months ago, maybe 6 months or so I put P-R on my DD's section of our calendar for tomorrow.
Problem being, I totally forgot what it stood for! A few months ago I remembered what it meant and I remembered saying to myself 'Thank goodness I didn't forget that!'
Now, I've forgotten again.. shit.
I don't usually use abbreviations on the calendar (and I'm not normally this forgetful, honestly!)
What could it mean? help! I don't have any tickets for anything booked for tomorrow..

How old is she? Is it’s school related?
Practice run, pre register?

Is there a Mom and her dd coming on a playdate? Patricis with her dd Rosie?
Are you mindind two dc for a friend: Peter and Rosie?

Does she have a play date with p and r. Is it a party?

She's mid teens so no playdates... The only reason I can think of as to why I put abbreviations is that it's a surprise for her, normally I wouldn't be so cryptic

I’ve done this a couple of times before, never did figure it out!

Is your house ready for visitors? Maybe you invited somebody and forgot. Otherwise, something to do with school?

Does her name begin with P?

Nothing to do with school I don't think..

Nope, it's not her initial.

Have you booked tickets for a concert/show?

Theatre trip? / theme park / shopping trip? / mother daughter day somewhere?

Someone's initials? Maybe a concert or a film you are taking her to?

Is it something you expect to be available now for to buy her for christmas?

Search your emails for tomorrow’s date?

Passport related ?? Pre register for something?? Something to Renew ???

Sorry, just read you've got no tickets - could it be that tickets haven't turned up because they are collect from box office? I booked a concert once 18 months before the event and completely forgot to go

Is it worth going back through emails with tomorrow's date as the "search"?

Something personal ‘I.e. Periods-Review’ if she were having problems with them, and so you’ve written it in ‘code’ so it’s not embarrassing for her being on the calendar?

Thanks for the help but no, none of these things I don't think.. I'll try and check my emails now and see if that sheds any light. I remember being so relieved I'd remembered so it must be something I've paid for, good point about not always receiving tickets, whats on at the moment that could be P-R? We travel to London quite a bit so could be something there..

Poetry reading?
Performance rehearsal?

Park run?
Pantomime reservations?

Park run? Pony ride? Piano recital? I really want to know what it is now . A few weeks ago I moved £1000 cash from its usual hiding place to put it somewhere safer. Can I remember where I put it? No.

I really need to know the answer to this now! Park and ride somewhere?

Anything to do with Prom Season?

Could it be a P for something like Photo so it doesn't register in your head as its a ph not a P if you see what I mean?

Nope, none of those.. shit Cross thats awful, have you tried your underwear drawer?
I've written it like it's P to R rather than P-R if that makes sense, like seats P to R or something.. The only sport/hobby she does is swimming and it's nothing to do with that..
