For me personally, my siblings are some of the closest friends I have. I am in constant contact with my siblings through weekly phone calls where we share all the new events in our lives. When we get a chance to visit it's an occasion that can't be matched as we have many inside jokes.
As for my younger brother, our relationship is less of a serious bond but more of a fun adventure relationship. When we get a chance to be with each other we find ourselves going and exploring new hiking trails, large cities around us, and tasting new food. When visiting back home he is my go to person to hang out with as it's a rare moment we get quality bonding time. Especially with his recent admission into the Air Force any chance to talk or see him is a good time. For my brother I am planning on sending him a beautiful bouquet of yellow and orange Lilies that are complemented by white Matricaria. If you have a family member in the military check on the conditions if they will accept gifts on their behalf.
There are only a few times in a year when you are reminded to take a moment to contact your family and give appreciation, and even fewer moments when you get a day to stop and reflect on your relationship with your siblings. As time flies by quickly, take advantage of these moments to reflect on these cherished memories and celebrate National Sibling’s Day. Especially if it's been awhile since you last connected with your sibling, take a moment to reach out, reconnect, and make sure they know how important they are to you. Taking a moment to let your sibling know how appreciative you are of them is important as you both recognize the value of your relationship and send them fresh flowers.
