<human>: This may sound silly but me and my fMIL are literally fighting over who gets to do the grooms cake. It's a BIG deal to me and traditionally it's a gift from the bride to groom. Now it's not JUST who gets to pick out and buy the cake but she also wants to have the grooms cake at the rehearsal dinner. We don't really eat sweets that much so I'd rather have both cakes at the reception where people will have the option to take leftover cake with them versus eating it at a restaurant and the rest going with us. I also just don't understand where she came up with what she is calling "tradition".

Condense the text into a few key points
<bot>: FMIL is trying to take the grooms cake away from me. How do I nicely but firmly tell her back the heck off.
