Woman gets birthday balloon from mom

I was visiting my mum for the weekend and she had come home and I thought that I was going to capture a really sweet moment of her giving me a birthday balloon for my 30th birthday but this is what I end up capturing instead. Woman visiting her mom, and sees her bringing her a balloon that says Happy 30th Birthday, and thought that she would get a sweet greeting, but her mom just went inside, leave the balloon in her room, then aggressively closed the sliding glass door then went on her way
