Kudos to you bro! Most guys that CAN buy an extra bike Do buy it. They might briefly impress a handfull of strangers. But few that Can buy an extra bike decide not to because its the right thing to do for the most important people... I hope that makes sense to someone. A stranger might say "wow! I'm impressed!" but is he really? While every little thing you do IS making a real and lasting impression on your kids... either positive or negative. Good for you on doing the right thing.
