Say one (or all of these) now and again...and see what happens :-)
- "I'm really proud of you."
- "I'm having a flashback to (insert a special day and time) example: 10 p.m. last Saturday."
- “Thank You”
- "Wine bar, 8 o' clock, meet me there."
- "I think that woman was checking you out!"
- "My coworker couldn't stop admiring those earrings you gave me."
- "You need to go to bed."
- “Let's turn it into a bet."
