I don't know we talk all the time and today nothings and I feel like I shoulda said hello earlier in the day and its late I dont want him to think its an after thought but I don't know if he's been busy or mad. And this the world of over analyzation !!!!!
Aww, dont worry, just say hi to your friend, tell them you're sorry for not talking to them earlier and then just wait for an answer. Maybe he/she won't see it until tomorrow though so don't get too excited
