I appreciate the thought, but then you almost feel obligated to keep it for a while, because someone bought it for you. Then there's the fact that if you don't get cards for Valentine's Day, Mother's Day, Father's Day, Anniversaries, Birthdays, and God knows what else, you're in the f*cking doghouse for it. I truly feel like they're one of the stupidest inventions ever.
The only time I could MAYBE see the use for it is in an instance where someone's sick or someone died, and a group of people sign it and send it all as one, but even then, the more thoughtful option is to make a phone call if you can't offer your thoughts in person. And it's a brazillion dollar industry. So ridiculous.
