149 is I love you. It's a combination of two other forms: 143 and 459. "I" is interchangeable with "1" and "4", love with "4" and "5", you with "3", "9" or "8" (8 represents a U on the telephone keypad.)

Other examples include: 448, 158, 449, 159, 148, 443, 153.

These examples exist because, when it's heartfelt, the sentence "I love you" can be the most frightening, challenging and intimidating sentence to utter. Frequently, less direct versions appear necessary in order to build courage for the real deal.

Get the 149 mug.
It somehow has accomplished what no one has ... ever! You have never had this feeling... you are not scared of it, but your feelings for it. How did it figure a way to your heart? How did you let this happen?

You don’t understand it... you try to embrace it... the moment there is any question, you are quick to retreat... however, it still consumes your thoughts. You try to avoid it, but you can’t. You want it ... you love it!!

You over analyze every moment still trying to control something you can’t .
149; trying to be a tough, but it appears to have the key...

Hoping this is posted ... and soon!
