The Best Movie I've Seen, Ever!

Rating: 9/10 (29 March 2019)

I have watched this movie countless times. It is the best movie for many reasons ever made in my opinion. The story, its values, acting, sets are marvelous. I rated it a 9 but I could be persuaded to give it a 9.5.
After all these viewings I have two questions for Frank Capra or anyone who loves this movie.
The first question is when George rescues his brother Harry. We are told by the second angel educating Clarence about George that he saved Harry's life - (George, Marty, Sammy and other friends were sliding down a snow covered hill on coal shovels onto ice and sliding across the ice covering a small pond open at the far end to the pond's water. Harry slid too far and fell in. George jumps in to save Harry), but he caught a bad cold and his left ear became infected and he lost his hearing in that ear. It was "weeks" before he was able to return to his after school job at Old Man Gower's drug store. The scene of the boys sliding was snow and ice - the next scene was George and his friends walking after school to George's after school job. The key word for me that raises my question is the word "weeks" because leaves were on the trees a very fast transition from the snow covered pond. I think a better word would be months. Another clue is that on the telegram the date is May. Any ice and snow would have melted back in March.
The second question is if Potter spends his time in a wheelchair, how does he get around with only the help of his large assistant? How would he AND the wheelchair get up the steep stairs at the Bailey Bros. Building and Loan? Does the assistant take the chair up first then returns and carries Potter. The chair looks like it's made of solid wood and is very heavy by itself. Are there duplicate chairs placed in Potter's office and places he does business so the chair does not have to be considered? And how does he get up into his horse drawn carriage? It seems so easy for Potter to be anywhere. Perhaps Capra is counting on our imagination? Any answers out there?
