My husband started a new job recently. We began by setting his 401K at 10% to see how it would go, and increase it from there. (Yes, sorry to say, we are not yet maxing them out). Yesterday, I ran the numbers, and emailed him to tell him to raise it to 20% (the company has a limit of 25%, and I am hoping to raise it to 25% soon, if we find we can survive with the 20%).
Anyway, apparently as he was doing this, one of his coworkers was watching him over his shoulder (rude!), and started asking him how he could possibly do that, and what he was thinking. She said she is only able to put in 2%, even though the company matches up to 4%. He basically told her that's why he brings lunch every day instead of eating in the cafeteria, and why he doesn't join them for drinks every Friday. I seriously doubt she got the message, but hey, maybe it planted a seed.
