How do you avoiding missing someone?

answer: hang out with someone else or occupy your mind with something else. : )

go nd find someone else and then again find someone else if u get bored of them

by looking at someone you know and chat with them or look on something like a painting or anything then the person or bring a book with you and act like you reading something or think about something that you like so you can spaceout and not put attention to what is happening around you .
