I forgot to close the other tab and now I see this? Well here's something for you:
Mom, though we may not always see eye to eye or understand what the other is thinking I want you to know that I'll always love you. You're there when I need you the most, and I couldn't find another mother like you anywhere else. Happy Mother's Day, from (Insert how you want to be seen. Son, name, etc...)
Change it as you see fit if you think it'll help. I really need to go to sleep now.
