I usually can tell when my roommates are not in a good mood the second they set foot in our room. Or if people indirect tweet me (this one is easy tho).
On the contrary, it's hard for people to know my feelings. It could be a blessing or a poop, depending on the situation. I can hide it when I'm mad at people but yeah, people hardly ever notice that I am mad. God... Why is it so hard to tell people that you're mad without actually telling them
Ps: i notice everything I just don't feel the need to respond or justify myself to you :-)
