Ignore my horrible spelling

Why does YouTube decide to stop loading at really bad times

STORY TIME
So yesterday I was watching danisnotonfire and amazingphil and well it was amazingphilisnotonfire 6 and for people who have watched this you can guess where it stoped well if you haven't watched it I suggest you do and welllllllll it stoped right as Phil is like "oh my flys undone" then it decides to buffer at that exact moment mum walks into my room and I'm just like "shit" cause it looks really bad for somebody who doesn't know the beginning of the video and..... The context is that Phil is like "my flys undone" walks out of room and yea but where it bufferd it kinda looked lets just say it looked really bad.. And well it went kinda like this "Sydney what the hell are you watching" and me being my socially inept (don't judge my spelling) self I was like "oh bad timing that's just an add"*turns off phone* and well yea

STORY OVER

Lesson here is if a video buffers explain to the person who walks in what the context is and not be a socially inept person
