Sneaking objective help

Sneaking dragon

Okay so I'm a super casual player but there have been a frustrating amount of times I'm grabbing a dragon or grubs solo and my laners come to help ignoring when I ping them not to. It's great when we have a wave crashing and the enemy laners are busy but so many times they just drag their problems to me.

I'm sure I just need to communicate better but typing is hard for me while I'm trying to concentrate. Does this happen to others, or am I just playing weird? Should I stop objective early if I feel it won't be favorable when they start pathing? Is there shorthand for act natural pretend I'm not here?
