I'm so bad at initiating interaction that I have to intentionally come up with ways to make other people approach me, because I just can't seem to make myself approach them. I will go to open mic nights to perform my music or I will sit somewhere, drawing in a public place where people will see it, just because it is easier to get attention for those kinds of things than it is to try to get up the nerve to talk to a stranger. If someone else shows an interest in something I am doing, there is an instant topic of conversation, and it isn't so awkward, because that person is coerced into making the first move.
That INTP poster is the kind of image I was originally looking for, but when I found the baby at the computer, I thought it would suffice.
