<human>: Can you condense the text into a few key points?

So my mom received an email a couple days ago saying that my biological father will be in town. He says that he truly just wants to see me and my sister, even if it is just from a distance. My sister was very against this and even thought that this was a bit weird. The decision is up to me if I want to go out and meet up with him. He talked about how he lived on less than minimum wage to pay child support. Truly I feel sorry and want to meet with him. I'm just not sure if I'm ready to do so yet. He says he will only be here for a short amount of time.
<bot>: My father who I have never met wants to see me, I feel I'm not ready but this could be my only opportunity. What should I do?
