As we all age, we have the tendency to move consistently from state to state or country to country. Friends will understand that we cannot always keep in touch every single day and visiting them can be challenging with all the planning. But, a simple text or a short conversation can make them happy for the rest of the month. I personally love that my friends are low maintenance. We are the type where if felt like just yesterday we say each other. This is a great indicator that you are close with them. I do like to send them a message once in awhile and when they message me back it makes me so happy. I think if we just check in with them once a month can help them realize that we care about them. I truly think this is the easiest way for people to make their day or month. Check in with your friends can say hi.
