In this case, signs I should trim my mustache:
- When wondering idly about getting something to eat, discover a snack in my mustache.
- When kissing a woman, I end up with hair in my mouth.
- Be woken up by the kitten nibbling on my mustache.
- In a strong wind, notice it tugging on my mustache.
- Every sip of beer is followed by sucking more beer out of my mustache.
- Napkins become a permanent fashion accessory.
- Drinking soda from a bottle involves the extra step of positioning the mustache over the top of the opening.
