She's the type that really doesn't want or need anything but I can't just not get her anything....thats not how i am...anyone have any good things.....what could i make her....somethin sweet & easy....? I don't know around christmas ish....I got her a 2Kt gold bracelet and we went to a hotel....that was a lot though....this doesn't need be like that....just somethin to get the message across and say goodbye before she leaves for the 6 weeks.
any ideas are appreciated.
