Scooter, mobility scooter?
Dont feel stupid if you have to use it, if you have to use it as a time to time or last resort as im sure some days of mobility are harder for you than others.
Can you order the shopping in rather than having to rely on your partner to get it right? if its a problem get a printer go online and print images of the things you want and make sure he cant get it wrong.
Mice? my T's and i can sort that problem
find the enterence and stick a very large mouser there (hunting cat)
Time takes away the last few moments..
