>>20030445She isn't a liar, she's just a dummy who commits herself to shit while having fun in the moment, but later forgets about it and the idea is purged until someone reminds her. Honestly, her habit of nonchalantly saying "yeah, let's do that someday" is annoying not because she doesn't commit to what she says, but because autists get uppity not knowing that it's a figure of speech displaying interest in said subject, and not actually a commitment. This is common in daily conversations, but of course these idiots never leave their house.
