A 'D' Birthday

This boy is the younger (by about 6 years) of two boys.  He's small for his age, too, and is babied (in my opinion) by his brother and dad, who are always in the lessons.

Boy's dad: You might notice a slightly different J this week... [babying voice] Because he's had a birthday.
Me: I thought so!  So you're 9 now, aren't you?
Boy [downcast]: Yeah.  [pause] But I want to be 8 again.  I liked being 8.
Me: I understand.  Not much you can do about it though.
Boy's dad: Maybe, we should not have any cake, or presents, tomorrow?
Boy: Could I have a 'D' party?
Me [in my head - a what?  Have I misheard?  Am I really getting so old and behind the times...?]
Boy's dad [after a slight pause, with a look of confusion on his face too]: A what? [phew]
Boy: A 'D' party.
Boy's dad: What's a 'D' party?
Boy: You know.  Where I get a 'D' and have to go back to being 8.

Ah.  So, failing at being 9.  Not a bad concept.

Birthday Swap

9-yr-old boy. 

Boy: Oh... That concert isn't on my birthday is it?
Me: When's your birthday?  It's in May, right?
Boy: Yep.  May the 24th. 
Me: And you're turning... 9?
Boy: 10. 
Me: Well, that explains why you're so tall.
Boy: Oh ... Wait... My dad and I are swapping.
Me: You're swapping?
Boy [starting to giggle]: Yep.  He's going to be turning 10, I'm going to be turning 39.
Me: 39?!
Boy: Yep, I'll be 39.  So... Actually... My birthday is now going to be April... No... March 30.
Me: Wow.  So you'll be the oldest person in your class!
Boy [big grin]: Yep!

Teenage Birthdays

15-year old girl, whose dad comes to every lesson.

Dad: Next week, L is in exam block, so we won't be coming to a lesson then... And the week after that is her birthday.  She tells me it's in her contract [smiles] that she doesn't do lessons on her birthday.
Me [smiling]: Oh, I understand.  I totally agree with that, actually.  So how old will you be turning?
Girl: 16. [Grimace] Ancient.
Me: What's that?  Ancient?
Girl: Yeah.  16 is ancient.  I will be ancient.

Birthdays and Getting Old

Girl:  Oh wow.  I just realised, when I see you next time, I'll be old!  It's my birthday next week.
Me: Ooh, what day?
Girl: Wednesday.  I'm turning 15, so I'll be old.
Me: Okay... [We talked a bit about birthday activities]
Girl: We've got so many tests next week, but none on my birthday -
Me: That was nice of them.
Girl: But there are four the next day.  Oh, and mum had me sign this Medicare thing -
Me: Wow, you are getting old!
Girl: - and I just signed it -
Me: Ooh, you should always check what you're about to sign.
Girl: I know!  But mum just went, like, agh! [high pitched 'mother' voice] You should always read it first before you sign! [normally] But I'm, like, you're my mum, I should be able to trust you!
Me: One would hope so, anyway.  So, why is 15 classified as 'old' now?
Girl: Well, because I'm born in November, I'm older than most of the girls in my grade, so they're all teasing me, saying 15 is half-way to 30... which it is... So I'll be old soon... [sad face]
