yesterday, we, vlado and me, we were drinking with si vo. si vo went out of the pub and he wanted to make a grg. a grg is when you drink a lot of water and gas comes out of your mouth. but si vo was surprised, when he found out, that there was no grg, no, but there was suddenly vomit in front of him on the street. as no encyclopedia can explain this phenomen, we ask you to do that. please. for si vo. have a heart for animals.
