How Many Fingers?

I bought Alina glue-on fake nails for her birthday, as she had mentioned she would like some for our wedding.

There was a pack of 48 nails, both natural looking ones and ones with a golden pattern, to go with the gold theme.

Alina: So do you wear the natural ones one some fingers and the patterns on some?
Me: Well I guess you do as you like.
Alina: Oh yeah of course, there are 48 nails and you have 24 fingers, so there is enough for both!
Me: Exactly!
....

Me: How many fingers did you say you have..?
Emma: (laughing hysterically) This reminds me of the time you though that hares have three legs!

(Footnote: Alina is actually a highly intelligent girl who finished school with top grades.)
