<human>: I've been seeing this girl I work with for almost 2 months now. We aren't super serious or in an official relationship or anything like that. But I feel like I should get her something kind of special for her birthday, seeing as 21 is a milestone birthday. Only thing is I have no idea what's appropriate to get her. For most people I'd just buy them a nice bottle of what ever their preferred alcohol is but I feel like that would be too innocuous since we have been seeing each other for over two months. On the other hand I don't want to go too big like expensive jewelry because I think that would be inappropriate and would send the wrong message since she and I aren't in a committed relationship yet.

I'm not sure if this is the right subreddit to post this question but I could really use some suggestions or advice on what to do.
