Rush hour, I get on train and plonk my bag on an empty unreserved seat, ready to take coat off and sit down. Next to seat sits a perhaps 14 year old lad, on a reserved seat. Across the aisle his mum and dad, opposite me his teenage sister. Just as I want to sit down (my stuff already there), dad shouts to son, move on that seat, yours is reserved from here. I look perplexed (no other seats available) and say, ahem, no? I sit here. Dad shouts: he was sitting there a minute ago (he wasn't when train pulled in!). I'm trying to think of something to say, dad gets out of seat and approaches me as if he's going to either thump or manhandle me and says, you move! I get seriously pissed off and sit down, saying "ABSOLUTELY not". Kid laughs and put his reserved ticket on my seat, and says, now you are in the reserved seat. I smile mildly and explain about seat numbers. Now he's sittin opposite me, in an also reserved seat (he was lucky, they didn't come) and the whole family glares at me. Kid keeps mentioning "bad smell"I've got an hour on this train, very unpleasant. Mainly I'm shocked, am woman in mid 40s. WIBU?
