Just wondering for those on instagram/fb, do you have a 'friend' whom you follow who posts pics of their DC almost every day & you press the big like button, but when you do it say, once or twice in a blue moon they never do, even though you know they follow you? Part of me feels this is a bit petty, but actually its a bit rude to never react to your pics. Probably BU just wondering other peoples take on this
