<human>: My parents broke up when I still a baby, and my mother left me to be raised by my father and his parents and family. I had a very happy childhood and honestly, never felt like anything was missing. My father's family would tell me stories about my mother and her family, and everything they told me portrayed her in a good light. So it's not like I grew to dislike her or anything. She would occasionally call me and when I was seven, she visited and spent the day with me (she moved to a different country after the break up). As I've said, these circumstances never upset me or made me look at her askance. When she'd call, it would be like hearing from a fun aunt in a distant, exciting place. 

I visited her once when I was 16, and we've spoken on the phone a handful of times. The last time we spoke was last year when she called me to wish me a Happy New Year. I said I'd call
her again soon and then...I never got around to doing it. The thing is, there is no sense of urgency to do so, and that seems to be the dynamic between us. 

I wonder how healthy this is, and if I eventually come to regret this. As things stand, if I was to hear that she died, I don't think I'd be able to summon any tears. Sure, I'd feel sad, but it would be the emotion I'd reserve for a really nice neighbor. Should I make more effort to build up a more intense relationship with my mother, or just let things continue to go as they've been?

Can you give me the gist of the text in a nutshell?
<bot>: Should I make an effort to establish a more intense relationship with my mother, with whom I share a very casual, wishy-washy relationship?
