Strangers or Angels

Yesterday, I decided to take my child out for his birthday. Honestly, I was low on funds, so I had decided to charge the meal and pay for it later. 
I asked my son where he wanted to go, and naturally, he wanted to go to a nice place. I was not concerned about the price anymore because I had made up my mind to charge the meal.
So we are seated at the restaurant and there is a lady present, reading a book. I spoke and sat down. I wanted to ask her what she was reading, but she looked liked she did not want to be bothered. It was really bothering me that I could not talk to her, I love talking to people!!! 
My son and I talked about his birthday, his new experience at the restaurant, and various other topics. We got through the dinner without talking with our companion. The checks came and you know what.......
She pulled out cash money, laid it on top of my check and said, "happy birthday". I could have cried!! I was shouting on the inside. After that, she explained, she did not have much to say because she was tired, had just arrived back in Atlanta, and just wanted to relax. We talked about our children, schools, and other topics right before leaving. I did not mention to her just how much she blessed me, but I thanked her!!  
I hope she reads this post today, because she was truly my angel last night. Thank you God!!! God sent me an angel last night and I'm very grateful!!
Be not forgetful to entertain strangers; for thereby some have entertained angels unawares.
