If I had a time machine, I would do so many things!
Firstly, I would go back in time to those days when I had been mortified and embarrassed and try to alter it for the better.
Next, I would go back to when things weren’t as costly as today. I would treat myself to hordes of cheap chocolate and ice cream!
I would also go back to famous historical events to see how things were and try to see if I can stop something like a war.
However, if possible, I would return to my childhood days and try to be stuck there!
