If you go to Watt brothers at the top of Hope Street (the street next to Central Station) in Glasgow, you will find a wool department. It is a really old fashioned department store, full of bargains. It's like a warren, so ask the shop assistants for help.
No-one ever comes out with just what they came in for, as I can testify today.
Forgetting where you left your keys does not mean you are “losing it”
