Madly in Love
Engineer is a straitlaced fellow.
He doesn't walk around in a smiley stupor like someone else in this household has been known to do...
This is not to say that Engineer isn't happy, pleasant, or at the very least cordial, he just isn't what one might call jolly.
That being said, Engineer does have a certain twinkle in his eye that I adore.
When he's trying to be serious and I am smiling at him (as I tend to do when he is serious) he gets a faint upturn of the corner of his mouth and a very distinct flash in his eyes...which leads me to swoon.
1-4-3 EM and that gorgeous light in your eyes.
