That's so sweet. I can relate! My first day at Riot was League's world championship finals in 2013. My mom (she is not a gamer) was so supportive of me that she watched a bunch of group stages with me before she helped me move to California and she went to the finals with me as my +1. And she kind of knew what was going on because she said something like "I thought they would win, they had more gold!" at one point.
It was a big deal to me because I had made a huge career switch by joining Riot and I was moving across the country to join Riot, so it meant so much to have her take an interest in League. She's been really supportive of VALORANT too, watching trailers and stuff I send her.
