I tend to use lots of emojis so folks know how I feel (that I'm not in a bad mood) because misunderstandings have happened before.
Sometimes I however also use an exclamation mark as saying something happily, without emojis. I know this can mean the contrary to that what I intend to say to some message receivers.

Make sure you explain calmly to folks what you think/feel if they question or even attack against something you let out! Misunderstandings are stupid, they can be avoided and fixed, and people's days can be not-ruined ❤
