I too am deeply perplexed by Uncle Tim's absence

I feel though that he is visiting and keeping and eye on things as his presence has been noted
I can only assume that he is wrapped up

either in the new love of his life

or still in the packaging in Heat's house
Either way I'm sure he's fine and will join us shortly
In the meantime to waylay your worries I think you should book an opticians appointment to check your eyesight! a hearing test because it's just not normal not to hear voices! but I don't think you need the psycologist yet as your not being ignored
