We have plans with my mom for brunch in the morning so FI checked in with his parents to see if anything was being planned to make sure we could do everything/see everyone on the day. They don't have anything organized so we'll likely just swing by on the way back up to road to visit for an hour or so.
Of course FI is giving his mother a card. I was just at the store getting cards for my own reasons and noticed they have a lot of generalized Mother's Day cards now, not just for your birth mom.
Are you getting a card like this or flowers for your FMIL? I'm struggling to decide if I think it'd come off as a nice gesture of being excited/happy to have her as a MIL or awkward and out of place like I'm trying to share in/take FI's thunder (not that I would he IS her son but you know what I mean..)
