Is it my job to remind coworkers when they forget to schedule meetings with me?

I've been given basically no work at this new job I started in mid May. A coworker emailed me saying he'd send out a meeting invite to me so he could walk me through how to do this request he got. He never sent the meeting so I'm not sure if he forgot or just did it himself. I asked my mom and sister and they both agreed it was my job to remind him. Thoughts?
