One of my best friends in Highschool and for years after was born on April Fools day. Man we had some good times playing pranks on him. He always laughed harder than any of us at the pranks.
Years went by, we drifted out of contact as we all get busy with life, and then through a series of circumstances I learned he had killed himself, almost ten years ago now.
If you have friends you've not talked to in awhile, make an effort to reach out to them.
