Angry? Upset?

Should I be angry or upset?

I realise my bro had been eating my bird nest as dessert and 3 bottles were gone when I realise it. 

Its kinda expensive as even I hesitate to open up n eat..

N I'm being blamed to left it in the fridge..

Sigh.

Fair or unfair? U decide. 

I will decide on whether to be angry or upset.
