Missing

Missing someone isn't replying "I miss you too", once in a month, to messages they send.

Missing someone is wanting to find the time, or even make the effort to make time to meet, or at least talk to them. To discuss what's been going on in your lives. To do things together. Things that you've both enjoyed, that've gotten you together in the first place. Because, yes, life goes on and shit happens all the time. But if you miss someone, it means you're interested in them and you want to spend time with them.

Missing someone isn't having them on a list and not bothering to contact them, only to barely wave back at them when they eventually try to reach out to you.
