How can I not go to work drinks.

Got invited to work drinks, 

but am a bit broke, 
bit sullen,
besides,

I need to get fabric to dye for school

and I'm working at donuts all weekend.

Told the girls, 

who discussed my declination..

(I hope declination, is a word because I've used it a lot this year).

k: "ugh!  do you know Jett is abandoning us in favour of lincraft?  how lame!"

h: "actually i support her in that endeavour."

k: "over hanging out with us?!"

h: "well she's dyeing."

k: "she is NOT.  she's just over-reacting.  she was supposedly dying this morning and she's totally fine."

h: "no seriously, she's dyeing.  she needs to go get the dyes today."

k [pause, looks confused]: "...what?  oh you mean DYE-ing.  oh.  well, that's still not a good enough excuse."

P.S. am totally dying.
