When I see a comment I like or a comment that makes me smile or a comment that I perceive as advancing the conversation - even if it doesn't match the other two requirements - I upvote.
It's pretty rare that I see a comment that gets a physical or vocal reaction out of me. This is only the second one I can remember on lemmy. Your comment made me literally guffaw. My opinion isn't anything special, but it's all I have to offer and I want to make sure you know you had an impact on me. Thank you.
