Cooking class 1
Do not give a mom a cooking class for Mother's Day! That's like saying, "Hey, your cooking could totally use some work!" It be better if you signed everyone else in the family up for a cooking and washing dishes class. Then the mom in the family could reap the rewards.
Magnifying mirror 2
Personally, I think magnifying mirrors should be banned. No one, but no one needs to see their pores enlarged to the size of craters. EVER.
Garbage can 3
If "mom" complains time and time again that the trash can is always full and no one takes it out except her, do NOT go and buy her a bigger trash can. That's not what she was hoping for.
Clothes that are the wrong size! 5
Just don't! My husband gives me clothes that don't fit all the time and it just makes me feel bad. Stay away from clothing as a gift for mom, give her a gift card instead.
