What would you do or have you ever been in a situation like this?

Threesome after Nana goes to bed🤣

Kiss my girlfriend while maintaining eye contact lol

Take Grandma outside and have a little talk with her about doing such things.

nice try grandma lol

Ask her if she is going to fix me one too.

I will leave gracefully.

Knock that plate outta her motherfuckin hands

Leave.

Hmmm ... start by assuming that the ex and your man are still friends, and that the grandma may have a good and longtime friendship with the ex. The plate thing was possibly a polite gesture, and the ex felt comfortable in grandma's kitchen, just an extension of their long term relationship.

fix me a plate and ask when does the three some begin

I don’t understand a word of this.
