My best friend was going through something last weekend I helped him through it. Today he messaged me and said thanks for being there for me Tiff. I really appreciate it. I did it out of my heart. Because I actually care about him. What does he mean when he says thanks for being there?
I know I should know what it means lol. Let me know what you think.
