Ok - can NOT resist the urge to reply.... THE COPS???? Are you kidding me?
For taking a picture of a piece of cake - which she brought to you to "inspect" & I would suspect can be considered as given to you (how else can you check it?) - Did she want the fork full you tasted back too? UGH- UGH! The cops were probably thinking - "SERIOUSLY?"
Kudos to you for keeping your cool...
As for the lawyer - if this goes anywhere, don't know if it would help but I'd consider baking the same size cake as well as a smaller one to take as further "evidence" of the baking process. So glad you had a chance to take photos - they speak a thousand words. Date & record everything in case she is that bored with her newlywed life & pursues this.
BTW Shouldn't she be on a honeymoon??? She is someone who seriously needs to relax! Sorry you have to go through this.... again - UGH!!!!
PS: as for trimming the cake - when I took a cake class & we had to trim we couldn't resist sneaking a piece of the "cake scraps" - the best part! Delish! hee!
