I am sure that I can confuse anyone.
Very often a conversation does not get off to a good start anyway as when I answer the phone I always say my number, a few people then just put the phone down, it rings again and I say my number again then they say I want Cats Protection, I say this is Cats Protection and they say why didn't you say when you picked up the phone, I then say well this is my private number and also my husbands business number.
Also I am sure you have all had it the phone rings you say your number and someones says I want xxxxxxxxx, you say sorry you have they wrong number and then it is your fault because they have the wrong number.
Lastly sometimes someone will ring and you know who it is before you answer, I sometimes will say I knew it was you and they say how, I will say I heard you dialing, it is surprising how many people say 'did you'. I first did this on mum (now sadly no longer here) she lived next door but one.
