Decided to adopt an orphan

At the age of 35, I'm still single. Everytime I go for dates, it's either the women dump me or I decide to not continue with my affair towards them. Just a few weeks ago, my grandma has been very persuasive about me marrying soon, or if not, just adopt someone from an

orphanage. I don't know what she's into but I can sense that she's really serious about me having a family ASAP. The latter idea of adopting a child caught me. I've been living alone in my house and adopting someone might be a good idea. While studying this out and looking for comments about adoption, I saw a testimonial in a marriage tours about the advantages of adopting an orphan, plus I'll get to help someone who's in need of a home and proper care. That's when I decided to adopt an orphan. Should I choose for the kid? I don't know the ways in doing so. I need your advice and critics regarding this. Thanks y'all!
