To protect the health and safety of your wife you can't endanger everyone else and create a fire hazard. The guy moving the chair around was being completely unreasonable and handled it incorrectly. However, you have acted like an entitled person yourself. In your own family and circle of friends you can be as entitled as you want but when dealing with others, it becomes every man for himself. Call me cynical but society has changed, everyone seems to be raised to look after number one and wants to sue and coz of that there are now absurd legal risk management considerations in life. We just have to deal with it. Save up, buy a ground floor space or you own house. An even better plan: plan everything in life including having your next child strategically, i.e. Make sure you buy an appropriate place where you can actually be considerate to your wife without creating hazards or upsetting neighbours. Make sure it's near a good school, safe garden to play in, etc etc. You have to plan strategically. I mean all this in the nicest way possible.
Not saying this necessarily applies to you but people don't seem to plan much at all nowadays.they buy things on credit cards knowing they can't afford to pay it, get themselves in to debt, have kids when they only got £500 in the bank and cry when they can't pay electric. They cry when bosses won't give them time of work at short notice.
Why be at the mercy of others when we can plan to be at the mercy of ourselves? This could be another thread topic haha
