<human>: Can you give me the gist of the text in a nutshell?

I am a male, 27, single for about 6 months, in a new city for the same amount of time. I was home this past weekend, and my grandma mentioned that her best friend had a granddaughter here, as well.  I didn't think much of it, because my grandma is always trying to make me happy and set me up, but she called today with this young lady's phone number. Now, should I just call? I am curious what a girl would think in that situation. I assume she expects some sort of communication, as I would assume her grandma briefed her in the situation.
<bot>: grandma gave me a young ladies phone number who is related to her best friend. Assuming she gave her the number for me to call, how do I approach it?
