... you post pictures of food all the time.
"Posting of food pictures can often be thought of as either a declaration about the self or an emotional request," Cilona points out. But there's more to it...
If you're posting exotic or unusual food that you ate, you're saying, "I'm daring and bold."
If you're posting decadent, unhealthy, and indulgent foods, it can be an attempt to alleviate guilt by eliciting responses that indicate that others relate, identify or condone.
If you're posting food or a meal that was greatly enjoyed, you might simply be sharing a great find with friends and family to also enjoy one day.
Cilona adds, your postings may merely show you want to share something great, but if your meals are consistently from expensive, elite and trendy restaurants, the intention is more likely related to creating an image or perception.
