When she just won't stop shopping and you really want to go home 

That really rare awesome moment when she shows up on time. All our moms give us the cart and disappear to get something else. We all know the struggle that ensues. We anxiously wait for her to arrive before it's our turn to bill. And sometimes she does! But most of the time she doesn't.  And then we all do the customary 'I can take all these bags in one go because two go's are for losers'. Which we manage somehow but we do make a fool of ourselves in front of others. Be that as it may, it is an adventure in itself and we really do love shopping with our mom. She's definitely the best and no one else can take her place.
