A good way to let someone know you care about them is to really be present when you are in conversation with them. This may be harder to do than it sounds. We are all so used to multitasking that it can seem odd to actually just have a conversation with someone, and do nothing else at the same time. Try it – it is amazing to be there at a deep level for someone, and it is impossible to do if you are reading, folding clothes, paying attention to another person, or doing anything else.
