1. Seriously, after 40, don't deliberately dye your hair jet black and shiny—a touch of gray is something men your age should be proud of. A greasy, glossy black mane just makes you look ridiculous.
2. Whether it's yoga, gardening, knitting, or shopping—you may dislike our hobbies, but you absolutely should not mock them. Otherwise... just wait and see.
3. Truth is, we crave those steaming burgers loaded with melted cheese just as much as you do. But our willpower to resist them is far stronger than yours.
4. If you're unsure about our relationship, give us a spa gift card for Valentine's Day. If you're certain about our relationship, give us a diamond ring for Valentine's Day.
5. Ha! Seriously, we don't mind your snoring—as long as it's slow and steady. That hypnotic effect beats staring at the ceiling counting "one sheep, two sheep" any day.
6. The cologne you wear should only be shared with the woman nestled against your chest.
7. A chiseled six-pack is our ultimate weakness—just like how you guys find cheerleaders in tight outfits irresistible. Fair's fair.
8. A well-planned date (like reserving a table at a fancy restaurant) guarantees us a perfect evening. But if you show up unprepared, just holding our hands and grinning, when we say "goodbye," it means "good riddance."
9. It's fine if you glance at beautiful women on the street. But if you're smart, you'll make us feel like you're stealing glances at us too.
10. When we tell you we feel "something's happening," you'd better come clean quickly—because we have a nose for sniffing out the truth.
