Re: Nudism
Nothing wrong with wearing a dressing gown only, I do that most days until late morning. A leftover from working permanent nights for two decades, I just don't wake up properly until late morning.
Accepting deliveries shouldn't be a problem in a dressing gown, I often do that and just say "sorry, just woken up".
My washing is seldom put out as I put it all on a clothes airer in the utility room where it dries very quickly. If I do decide to put it out then I do so leaving it on the airer, standing it on the patio in the sunshine, that's not very often though.
As you say you 'only have the lads here' can they not put the rubbish out on the right day for you?
No reason why you cannot water the garden wearing a dressing gown either I wouldn't have thought.
A Scotsman has no problem when wearing only his traditional kilt (so I am told) so no reason why you need to see it as a problem –"needs must" as the saying goes!
All you describe sounds like a serious problem, hope you soon recover and can continue getting on with sorting your new place out.
