tezestwing you don't mention what kind of activities your neighbour is complaining about. What may seem to be perfectly reasonable to you may be totally unacceptable to your neighbour even if the activities are carried out on your land , particularly if it affects his enjoyment of, or is detrimental to, his property and if that were the case, the law would probably be on his side. Hopefully, you do not retaliate with the verbal abuse . By far the best thing would be to try to reach a compromise with him-some give and take in other words.
