It's easy, you have to concentrate. Envision riding a fiver along to the shop; milk, bread, biscuits. Place on the counter, into a bag. Pay, put change in bag.
Really concentrate on the bag, moving it takes effort! Bring it back (avoiding the lamppost I bent moving Jean's cooker!), and remember to unpack, and lock the door.
Make tea – you'll need it. I'll be back at six, students come at seven. Best put the ornaments in the sideboard, until the beginners are done!
Imagine when everyone can do it! Then you'll have to join in, lazy bones! Carpe diem!
