Watch out for acute enteritis

It suddenly got cold, and enteritis is going around.
Yesterday, I went to a pet shop run by a close younger friend.
As luck would have it, the Black and Tan dog he keeps had enteritis.
I played with it for a bit, came back, had a light dinner,
and went to bed early, but my stomach started making thunderous noises.
I went to the bathroom, and it was a total faucet~ Just in case, I washed my hands
extremely thoroughly before eating (I had grilled fish outside).
The cause is unknown, but it is definitely a time to be careful of enteritis~
I guess I'll have to use my mom's secret plum extract technique... sigh...
