Emotional about the dumbest thing- so frustrating!

Ok so the whole pregnancy i've been totally great mood wise as well as health (very grateful for an easy 1st pregnancy), i havent even cried once over literally anything....EXCEPT!!!!! - anytime i hear a hawaiian song, see something about hawaii on tv, sing a hawaiian song, etc. it makes me choke up & start crying...even if I'm at work! I love listening to the music too so its a vicious cycle- listen, cry, stop music, replay. listen, cry, stop music, replay.
