Yes I think even the most sense squigs would ask "where's the puppy" if she posted all of the Glasto stuff.I also think she’s deactivated to go to Glastonbury, removing access to her social media is the only way she can control the narrative. It’s quite sad really that she can’t just not go on Twitter rather than a loop of activation/reactivation.
Or she's having/performing a case of the bad mentals or similar as an excuse to get out of the Glasto gig because she's realised she can't leave the dog with friends/parents.
