Mayweather, who is set to fight
"If you're not in the position, you will never know," Mayweather said in a video posted to Facebook. "Some days, you want to go out and not sign autographs, or you want to go out and not take pictures."
Mayweather, in the video, is surrounded by a throng of fans while walking around Las Vegas as he talks about the issue.
"It hurts my feelings sometimes, but, you know, I have to say 'no' sometimes," Mayweather said. "I don't say 'no' to my fans because I don't want to sign for them or because I don't want to take a picture. I'm saying 'no' because I feel like it's OK for me to take time off for myself and for my daughter."
Mayweather has been posting videos and photos of his training for the Pacquiao fight since the bout was announced.
Including pay-per-view and the astronomical prices of tickets to the bout, the fight is anticipated to be the most lucrative in the history of the sport.
