Nice guys want to be helpful.
Guys generally want to be heroes.
If you need a guy's help, then accept it graciously. I don't have upper body strength, and so welcome manly muscles when I have to turn a stuck screw or lift something heavy. I welcome the help of someone who has abilities I don't have.
Being prideful ("I can do it myself!") doesn't help you, and it cheats him out of the opportunity to use the gifts God gave him.
Being a good receiver is as important as being a good giver.
Whose help will you receive today?
