I had a lot of imaginary friends growing up. I know, big shocker. I had a difficult time making real friends when I was younger because I was very bookish and frankly, overweight with bad hair and a gap between my two front teeth (which I still have), and kids being kids, they’d rather pick on me than play with me. So, I was alone pretty much until high school. I didn’t have imaginary friends when I was like, 13 years old, I outgrew those when I was maybe 8 or 9, but that didn’t mean I had a whole slew of real ones to replace them. I don’t think there’s anything wrong with kids having them, either. As long as they don’t keep them when they get older, and it doesn’t begin looking like psychosis rather than cute, childish whimsy, I wouldn’t worry about it much.
