Literally, everyone needs help, at some point in their life, hence parents...
Some people can learn things themselves, then they get old and need help again, or they catch an illness, or become injured, we ALL need help, and there is NOTHING embarassing about asking for help.
If you want to act macho and believe you can do everything alone, your life probably won't be as furfilling.
Anyway, what does it matter? I love speaking in stupid/silly/interesting voices and if this guy needs someone to help, it makes ME feel good to contribute, why do you always have to be a d**k about it? Some people just like being nice.
