I created a heart by typing in notepad. The heart is filled with "LOVE".
Step 1: Open
Step 2: Type the Outline
Type the outline of the heart the best you can.
Step 3: Type "LOVE"s
Type a bunch of "LOVE"s into the heart.
Step 4: Put in Paint
Press "Prnt Scrn" and go to Microsoft Paint. Right click and press "Paste". Maybe even add "Happy Valentine's Day!" next to the heart.
