We should actually be alright when that happens though. The actual things in each Galaxy are still so far apart that most will miss each other. Heres Neil deGrasse Tyson talking about it on StarTalk.

'Should' and 'will' are far apart when we're talking Galaxies :) I listen to Star Talk all the time, btw. Even Tyson would admit that he can't say for sure. Not that I'm saying for certain it will happen, all I'm pointing out is when you're talking billions of years, many, many unforeseen events can occur. Heck, a planet going supernova at the right angle would potentially strip the atmosphere right off the planet and irradiate all life on Earth. The thought that we'll definitely be around in 5-7bln years is...well, human levels of ego talking :)
