Of course you want to put your mother in the spotlight on Mother's Day. It's a great time to let her know that she's special and that you're thinking of her. You may want to thank her for her support, her wise counsel, or for always being there for you. You can of course give a beautiful bunch of flowers, but also a nice plant or candles as a surprise.
A good moment to reflect on motherhood. It may be the most common task in the world, but that doesn't mean it's mundane.
