Animals can communicate by
making nosies
making gestures
phyisical contact
using scent or odors

I would making noises(A), why?
Cuz' we do not understand their language, but they actually do talk.
Our ears are just closed from understanding there language.
Also, look at the fish, only after people have created a microphone thing, then only at that point we know now, that fish make noises, and our ears were closed!!! only after the scientists made the thing, then only we now know that there are noises in the water.
Hope that this would help you! =)

making noises

Animals can communicate by making noises. The noises made by an animal is a form of communication in which only animals understand. This is a way of informing other animals of what a certain animal has discovered. 

This is s cute awee : (( . well if she's showing you signs that she may like you , then shoot your shot ! don't be afraid . & if you're unsure that she's giving you these signs , then wait out for a little bit . most girls are different . some may act really sweet , but only bc you're a good friend of hers . that , or she might like you . you just never know . but i think you should sit down with her & tell her how you feel . but don't be awkward & shy . just be straight up & tell her how you feel . if the feelings aren't mutual , then don't cry about it . you need to respect her decision & look for others in the world . feelings can be difficult & confusing , but don't be afraid to show them . i say you play it out & if you're still unsure about it , talk to her . - rach
