1. Stay in bed
Though, your bed doesn't necessarily have to stay in your bedroom
2. Eat soup
Soup is extremely good for getting better. Make everything you eat into soup and you'll be back to normal in no time.
3. Keep an active mind
Not being well enough to do things can be annoying, but you can read books and play games to pass the time, so it's not all bad!
4. And, finally, your nose is running....
...you should probably catch it!
