because for us every day is special
Because it's an anniversary of the occasion, not the occasion itself. 365 or 366 days have passed since this last time this was celebrated or originally occurred. Honestly, think about it, make new memories don't attempt to glorify the old ones. (I feel the same way about my own birthday.)
Absent minded - That's me
My mind is a chaotic mess and I'm always thinking about five million things, so I forget
they're focused on something else.
I'm sure you were already expecting an answer like this one, but not all guys are the same and not all guys always forget special occasions. Honestly though, it usually means that to the guy this "occasion" isn't really that special to them.
Cause they're not as special to them.
